向量式自主起身椅 Lift Chair for Daily Life

傳統起身椅無法普及的主要原因是：
1.體積大，機構複雜
2.不符力學原理，容易讓使用者向前傾倒。
據人體起身時：重心移動與足部支點關係，配合不對稱槓桿，向量式向上、前推力，輔助起身少肌症者如銀髮族，可應用不同坐椅，動力替換功能，屬簡潔、高度商業化之起身結構。

​

The main reasons for the lack of traditional standing-up chairs are:

1. large size, complicated mechanism,

2. inconsistent with mechanical principles, making it easy for users to fall forward.

The traditional lifting chair mechanism does not consider the principle of human body lifting: the center of gravity of the body and the feet need to be perpendicular, so the elderly tend to fall forward.

This chair uses the asymmetric structure of scissors, so that users can easily get up safely, and can be used in different fields to meet the needs of commercialization.
