Description

A kind of sleeping berth lift headrest and a kind of sleeping berth using the headrest

Technical field

The present invention relates to a kind of sleeping berth lift headrests and a kind of sleeping berth using the headrest.

Background technique

Currently, usually using pillow on sleeping berth, height is fixed, and medical research proves that pillow is excessively high, too low or do not have to pillow It is unfavorable for health.High pillow easily causes stiff neck, cervical spondylosis.Low pillow easily keeps blood supply unbalanced, not bolster head, after excessive when people lies on the back It faces upward, easy mouth breathing, and then generates that dry, tongue is dry, has sore throat and phenomenon of snoring.It lies on one's side not bolster head, the neck on one side Muscle also due to excessively stretch drawing, fatigue and lead to spasm, pain, there is stiff neck.Pillow is too low so that blood supply is unbalanced, causes Schneiderian membrance hyperemia swelling influences breathing.It is exactly that pillow is too low or cause without pillow that neck and shoulder are ached after waking up from a sleep 's.

Furthermore sleeping berth is train, long-distance bus, a kind of facility indispensable on steamer, and when passenger needs rest, sleeping berth is needed It lays flat.Since existing sleeping berth paving cannot downwardly turn over, when being sitting in lower berth, stands or easily meet and discuss when sitting down, it is dangerous, it accounts for Big with space, passenger has sense of depression.And does not have to individually do backrest use, increase expense.

Summary of the invention

Present invention seek to address that the above problem, provides a kind of sleeping berth lift headrest and a kind of crouching using the headrest Paving, the blank that on the one hand it solves EMU sleeping berth, general visitor, long-distance bus sleeping berth, steamer sleeping berth are rested the head on without lift, solution Ordinary headrest is not adjustable the problem of height and comfort difference, provides one kind and is simple to manufacture, is easy to operate, being easily mastered operation Process, flexibility and sleeping berth lift of good reliability, bearing capacity is big headrest, on the other hand solving existing sleeping berth paving cannot It downwardly turns over and positions, the problems such as occupied space is big, the technical scheme adopted is as follows:

A kind of sleeping berth is rested the head on lift characterized by comprising
