Description

Seat capable of being opened and closed horizontally and lifted independently

Technical Field

The utility model relates to the technical field of nursing equipment, in particular to a seat capable of being opened and closed horizontally and lifted independently.

Background

For the elderly or patients with mobility impairment, especially for the patients with lower limb mobility impairment, such as the elderly with weak lower limb or the patients who have just performed the operation, the patient may only lie on the bed, perhaps with the help of the armrests, but the movement of the elderly or patients with lower limb mobility impairment (hereinafter referred to as the user) usually needs to be accomplished with the help of a movable seat, such as a wheelchair.

Wheelchairs are the most common type of seating apparatus used to assist in the movement of persons with impaired mobility of the lower extremities. When a user uses a conventional wheelchair, the user generally needs others to sit on the wheelchair, and then turns the wheels of the wheelchair by himself or moves the wheelchair by being pushed by others. However, it is very troublesome for people with weak lower limbs to sit in a wheelchair by themselves.

In view of this, there is a seat in the prior art, in which the opening direction of the seat is directed rearward, and the seat is detachable or unfoldable to both sides, and a support plate is provided in front of the seat. When the self-service wheelchair is used, the self-service wheelchair is pushed backwards to abut against the edges of other seats (beds, chairs, toilet bowls and the like) where a user is located, the user supports the two hands on the supporting plate to lift the hip slightly by virtue of the force, then the seat is installed or folded below the hip, and the user can sit on the wheelchair seat after sitting down. Because the supporting plate can be used for assisting the user to ride the wheelchair, the main strength of the user is concentrated on the upper limbs, the lower limbs only need to apply small force, and the user does not need to turn, so that the convenience and the safety of the wheelchair are greatly improved.

The inventor considers that the self-service performance of the seat in the prior art is poor, and other people are required to assist in installing or folding the seat. And because the height of the wheelchair seat needs to adapt to the height change of other seats, and the height can not be adjusted in the using process, the wheelchair seat is very inconvenient for a user to move among the seats with the changed height, and a part to be improved exists.
