Definitions

  • An operator seat on an industrial vehicle provides a recess in the seat back for receiving a safety harness or buckle. This allows an operator to comfortably sit in the operator seat while at that same time being attached to the safety harness.
  • the seat back may include piping that extends from or around the recess to further improve operator ergonomics.
  • FIG. 1 is a perspective view of an industrial vehicle seat designed to be used while an operator is attached to a safety strap.
  • FIG. 2 is a front view of the seat shown in FIG. 1.
  • FIG. 3 is a top view of the seat shown in FIG. 1.
  • FIG. 4 is a side view of the seat with an operator attached to a safety strap.
  • FIG. 5 shows the operator sitting back in the seat while still attached to the safety strap.
  • FIG. 6 is a top view showing the safety strap contained in a recess in the seat back.
  • FIG. 7 is a side view of an embodiment of a folding seat in an upright folded position.
  • FIG. 8 is a top view of the folding seat shown in FIG. 7. l DETAILED DESCRIPTION
  • FIGS. 1, 2, and 3 show a vehicle seat 12 that includes both a bottom seat 18 and a seat back 14.
  • the covering for the seat 12 may be made out of fabric, leather, plastic, vinyl, or any type of material.
  • the bottom seat 18 includes channels alternatively referred to as piping 20.
  • the piping 20 includes separate fingers 2OA, 2OB, and 2OC that all extend forward and then outward from a back end of bottom seat 18.
  • the recess 15 is alternatively referred to as a channel, groove, etc.
  • the recess 15 can be any length, width, and depth, but in one embodiment is sized to contain a safety apparatus 40 (FIG. 4) that connects a vehicle operator to the vehicle.
  • the seat back 14 has a substantially flat central surface area 19 (FIG. 2) that contains the recess 15. Rounded sides 17A and 17B then extend partially forward from the flat surface area 19.
  • the seat back 14 and bottom seat 18 include a cushioning material, such as foam, that is contained within the seat covering material.
  • the recess 15 is formed in the covering material and extends at least partially into the cushioning material.
  • the recess 15 extends substantially along most of the height of the seat back 14, around 1.5 feet, and has a width of approximately between 4 to 6 inches.
  • the depth of recess 15 can vary at different vertical positions in the seat back 14 and in one example may be around 6 inches at the deepest portion at the lower end of seat back 14.
  • the depth of recess 15 may be relatively deep towards the bottom of seat back 14 and may become shallower or taper towards the top of seat back 14.
  • the length, width, and depth of recess 15 can vary according to the type of safety device that needs to sit within the seat back 14.
  • piping 16A and 16B extend outward from the lateral sides of recess 15 towards opposite sides of the seat back 14.
  • piping 16C extends from a first side of the seat back 14, around a bottom end of channel 15 and to an opposite end of the seat back 14.
  • the piping 16 provides air circulation both into and out of the channel 15 and through other locations of the back seat 14.
  • the piping 16 and 20 can be any length, width and depth, but in one embodiment may be around one inch wide and about 0.5 to 1.0 inches deep.
  • the recess 15 in combination with piping 16 has the unexpected advantage of increasing ventilation along the height of the seat back 14 while at the same time providing support along the entire length of the operator's back regardless of whether or not the operator 30 (FIG. 5) is using the safety apparatus 40.
  • the pre-formed piping 20 in the bottom seat 18, and piping 16 in the seat back 14, is also alternatively referred to as channels and provide greater operator comfort by allowing
  • the seat surface to be more flexible and resilient as the operator compresses and decompresses the seat and as the operator moves in various directions during operation of the . vehicle.
  • the piping 16 and 20 also significantly increase breathability and comfort by reducing the overall surface contact with the operator and providing air channels to carry away operator sweat.
  • FIG. 4 shows a first operator position where an operator 30 is sitting forward on bottom seat 18 and is connected to safety apparatus 40.
  • the safety apparatus 40 includes a tether 32 having one end connected to a vehicle (not shown) such as a lift truck that is driven or operated by operator 30.
  • the operator 30 may be connected to an opposite end of the tether 32 either with a waist belt 34 or a full body harness.
  • the harness 34 is placed about the
  • tether 32 5 body of the operator 30 and is then connected to a bottom end of the tether 32 by means of a D-ring 37, or some other rigid connecting device.
  • the bottom end of tether 32 may include a clamp 38 that connects with a harness ring 36 via D-ring 37. Connecting to tether 32 improves safety by holding the operator 30 to the vehicle when the vehicle is in an elevated position.
  • Safety apparatus 40 includes D-ring 37, harness ring 36, clamp 38, harness 34 and tether 32 and is bulky and typically uncomfortable when the operator 30 sits down. For example, it could be painful for the operator 30 to lean back against a conventional seat back • while attached to safety apparatus 40. To prevent this discomfort, the operator 30 may sit in the forward position shown in FIG. 4. However, this sitting position can also be
  • FIG. 5 shows how the recess 15 allows the operator 30 to lean back in chair 12 without the discomfort of leaning directly against the safety apparatus 40.
  • the safety apparatus 40 is received and contained within the recess 15.
  • the back of operator 30 is supported by the sides 17A and 17B (FIG. 1) of seat
  • the recess 15 contains the safety apparatus 40 while the operator 30 sits more comfortably in seat 12.
  • FIG. 6 shows a top view of the seat 12 while the safety apparatus 40 is contained within the recess 15.
  • the shape and size of the recess 15 can be adapted to whatever type of safety apparatus is used to connect the operator 30 to the vehicle.
  • the seat 12 may be designed to let the safety apparatus 40 sit loosely in recess 15.
  • the seat 12 may be designed so that the safety apparatus 40 is snugly retained in recess 15.
  • the recess 15 may be just as deep as shown in FIG. 6, but may be narrower in width. This would allow the side walls of the recess 15 to snugly press against the opposite sides of the safety apparatus 40 keeping the safety apparatus 40 from freely swinging around in recess 15. This may also provide the additional advantage of providing more surface area on the seat back 14 for supporting the back of operator 30.
  • the recess 15 may also have the benefit of providing longer wear for the seat 12 by reducing scuffing between the safety device 40 and the covering of seat back 14.
  • the material used in recess 15 may be made out of a more rugged material than the material used to cover the rest of seat 12.
  • the material in recess 15 may be made of an industrial rubber material such as the type used for tires or wheel mud flaps.
  • the material in recess 15 could be made of a rugged leather material or possibly a metal material that is sewn into the material used for the rest of chair 12. Keep in mind that the back of the operator 30 typically will not rest against the inside walls of recess 15. Therefore, a more rugged and possibly less pliable or soft material can be used in recess 15.
  • the recess 15 may extend through the entire seat back 14.
  • the two sides 17A and 17B may be connected together with metal bars that extend through the back side of seat back 14.
  • a space between the two sides 17A and 17B operates as the recess for containing the safety apparatus 40. This would have the advantage of additional ventilation and provide further space for containing the safety apparatus 40.
  • a back support cushion including the recess 15 may be provided.
  • the back support cushion may be similar to the seat back 14 without a bottom seat 18 attached.
  • the operator 30 may lean against the back support while standing in an operator cabin, wherein the safety apparatus 40 otherwise rests in the recess 15 as previously described.
  • the back support cushion may be repositionable in a vertical direction to compensate for a difference in operator height.
  • FIGS. 7 and 8 show a side and top view of a folding seat 50 in an upright folded position.
  • a second recess 52 may be provided on the underside of a bottom seat 54 of folding seat 50 that may be folded against a top seat 56.
  • the recess 15 included in the underside of the bottom seat 54 may similarly retain the safety apparatus 40 when the operator 30 (FIG. 5) is standing and leaning against the underside of the bottom seat 54 in the upright folded position.
  • a first recess 58 may be included in the seat back 56, in the underside of the bottom seat 54, or in both the seat back 56 and the underside of the bottom seat 54.
  • a seat height may be repositionable in a vertical direction to compensate for a change in height of the safety apparatus with the operator 30 in a seated or standing position, for example.
