Technical Field
The utility model relates to an old nursing technical field, concretely relates to collapsible lift seat.
Background
In general, problems of the elderly people caused by the aging society can be summarized into various problems such as health, living, economic, social adaptation, and leisure. In the aspect of living, how to make the living environment of the old more comfortable and safer, the improvement of furniture is more important. Among them, the chair is one of the indispensable appliances in the home, and the known chair is basically composed of a chair seat, a chair back, armrests and chair legs. Although most of the existing office chair structures are provided with a chair seat height adjusting mechanism and a chair back inclination adjusting mechanism, the common office chair has the problems of unstable gravity center and easy falling, and is not suitable for the old.
Therefore, chinese patent publication No. CN110664553A discloses a back-riding type intelligent wheelchair for assisting the elderly in living, which comprises a walking chassis, a lifting device, a sliding seat, a backrest device, an annular armrest, an operating lever, and a telescopic bracket, wherein the lifting device is composed of a scissor fixing seat, a lifting scissor, a scissor electric push rod, a guide mechanism, and a scissor top seat. The sliding seat is fixedly arranged at the center of the chassis support and consists of a scissor top seat, a sliding seat cushion, a guide rail, a sliding block and a seat cushion electric push rod. The backrest device is fixedly installed at the rear of the sliding seat and consists of a turnover backrest, a link mechanism, a backrest rotating shaft, a backrest electric push rod and a scissor top seat, and the turnover backrest is arranged above the scissor top seat and is positioned at the rear of a seat cushion of the sliding seat.
The riding-back type intelligent wheelchair for assisting the elderly to live at home in the above prior art is also a lifting seat, and includes a seat body, a moving unit for driving the seat body to move, and a lifting unit (equivalent to the lifting device in the above prior art) for lifting or lowering the seat body; when the seat is used, a user controls the lifting unit to ascend or descend through the operating rod so as to adjust the height of the seat body, and the moving unit can be moved through the operating rod or a manual pushing mode. The existing lifting seat body comprises components such as a seat cushion, a seat back, seat armrests and the like, the seat body with the structure can provide a comfortable sitting environment for a user, but the lifting seat body has the problem of poor storage, so that the lifting unit (even if the lifting unit is reduced to the minimum) and the moving unit can occupy a large storage space, and due to the existence of the components such as the seat back, the seat armrests and the like on the seat body, the whole storage space of the lifting seat is further enlarged, the storage space of the lifting seat body is large when the lifting seat is in an idle state (indicating an unused state), the storage performance is poor, and the using effect of the lifting seat body is poor.
SUMMERY OF THE UTILITY MODEL
To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide one kind can provide comfortable position of sitting for the user when using, and can be convenient for fold the collapsible lift seat of accomodating when idle state to can compromise the use travelling comfort and the easy storage nature of lift seat, thereby can improve the result of use of lift seat.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a foldable lift seat includes a seat body, and a lift unit and a moving unit disposed below the seat body; the seat body comprises a seat cushion arranged on the lifting unit, a seat back arranged at the rear side of the seat cushion and seat armrest components correspondingly arranged at two sides of the seat cushion and the seat back;
the lower part of the seat backrest is movably connected with the rear part of the seat cushion; the seat armrest assembly includes a seat armrest disposed in parallel above the seat cushion, and an armrest support rod disposed below the seat armrest; one end of the seat armrest close to the seat backrest is correspondingly movably connected with the middle position of the side part of the seat backrest; the upper part of the armrest supporting rod is movably connected with one end, far away from the seat backrest, of the seat armrest correspondingly, and the lower part of the armrest supporting rod is movably connected with the middle position of the side part of the seat cushion correspondingly.
When the lifting seat in the scheme is used, the seat back is unfolded (namely, the lifting seat moves in the direction away from the seat cushion), the seat armrests can ascend along with the unfolding of the seat back, meanwhile, the upper parts of the armrest supporting rods can gradually stand up, when the seat back is completely unfolded, the seat armrests can ascend to the corresponding positions, and the armrest supporting rods can support the seat armrests, so that the unfolded seat back and the seat armrests can provide a comfortable sitting posture for a user, and the use comfort of the lifting seat can be improved; when the lift seat is idle, the seat back is folded towards the direction of the seat cushion, the seat armrests descend along with the folding of the seat back at the moment, meanwhile, the upper parts of the armrest supporting rods can fall downwards gradually, when the seat back is completely folded, the seat armrests can fall to corresponding positions, the armrest supporting rods can fall down completely, the seat back and the seat armrests can be deformed and folded simultaneously, the placing space of the lift seat is greatly reduced, and the easy storage performance of the lift seat can be improved.
