Mechanical structure of nursing wheelchair for patient, has trapezoidal support system that is supported by gas spring to perform angle inclination adjustment between seat and seat back portion with synchronous to each other

摘要

The mechanical structure has a main portion that performs mechanical adjustment between inclination of seat (3) and inclination of seat back portion (4) with synchronous to each other by performing angle inclination adjustment between seat and seat back portion. The angle inclination adjustment is performed by trapezoidal support system (2) which is supported by gas spring (6) to compensate for the shift in focus. The gas spring is attached to seat and is driven by linear motor.
