Background technique

Standing is a crucial factor affecting the independence of daily living activities of the elderly. It is a continuous movement process that mainly depends on the strength of the lower limbs of the human body and the center of gravity of the human body from a static position to dynamic balance. Standing precedes actions such as walking and going up and down stairs because a person needs to get up from a chair before walking. Many studies have found that standing up from a sitting position requires more muscle strength and joint range of motion than activities such as walking.

In order to solve the problem that it is difficult for the elderly with waist or joint diseases to stand up alone, there are some elderly assisted standing chairs on the market, which assist the elderly to get up by integrating the stand-up mechanism with the chair back and armrests. However, this type of seat has the disadvantage of low space utilization rate and inconvenience for some users with small housing area; and the mechanism is too complicated, it is difficult to maintain the chair, and it is easy to be damaged.

Aiming at the problem of insufficient lower limb strength of the elderly, we propose an assisted standing seat, which can be folded up and can be used as a cushion for assisting standing. Difficulty standing.
