[0048] (1) Overview and features of this embodiment

[0049] figure 1 It is a perspective view of the wheelchair frame 10 according to the first embodiment of the present invention.

[0050] This wheelchair frame 10 is a skeleton that constitutes a wheelchair, and it has a main frame 11, a back frame 12 integrally formed with the main frame 11, a seat frame 13 arranged along the main frame 11, and a seat frame 13 positioned and held relative to the main frame 11. The support mechanism 14 and the pair of intersection units 15 and 16 arranged as will be described later.

[0051] The wheelchair frame 10 of this embodiment is characterized in that the seat frame 13 can be bent together with the main frame 11 at the middle part of the seat frame 13, so that only the rear of the seat frame 13 can be tilted while the back frame 12 is tilted rearward. partly sinks downward; and the wheelchair frame 10 can be folded in the left and right directions through the above-mentioned cross u...

Abstract

A chair frame (10) for a wheelchair has a main frame (11), a backrest frame (12) and a seat frame (13). The wheelchair frame (10) also has hinge mechanisms (31), (38), (53), (56) for tilting and cross member pairs (15), (16) for folding. The main frame (11) and the seat frame (13) are divided into two parts along the front-rear direction by setting hinge mechanisms (31), (38), (53) and (56). The centers of the respective hinge mechanisms (31), (38), (53), (56) are located on the same virtual axis along the left-right direction. Cross member pairs (15), (16) are arranged in front of each cross member (31), (38), (53), (56).

Description

field of invention [0001] The invention relates to a chair frame structure used in wheelchairs used by disabled people, elderly people and injured people. Background technique [0002] A wheelchair is a tool for people with reduced mobility, and it can be used not only as a chair to sit on, but also as a mobility tool for moving instead of walking. Therefore, for wheelchairs, it is very important to allow users to use them comfortably, so some wheelchairs are provided with tiltable seats (for example, Japanese Patent Application Laid-Open No. 2003-190222). For the tiltable seat adopted by the conventional wheelchair, it has a seat part and a backrest part arranged behind the seat part, and when falling down, the backrest part can be tilted backward. [0003] For previous tiltable seats, only the backrest portion is inclined relative to the seat portion. Therefore, when the user is sitting on the wheelchair, when the backrest portion is lowered and then erected, etc., the u...
