ARTICULATING SEAT/CHASSIS INTERFACE FOR A WHEELCHAIR |
摘要 |
A wheelchair includes a rigid upholstered seat removably mounted on a crossbrace-type chassis. The seat includes a generally square-shaped frame having a clevis assembly depending from each of the four corners of the frame. Each one of a first pair of the clevis assemblies disposed at diagonally opposed front and rear corners of the seat frame is formed with aligned generally pear-shaped openings. Each one of a second pair of the clevis assemblies disposed at the other diagonally opposed front and rear corners of the seat frame is formed with aligned generally horizontal elliptical-shaped openings. An inverted generally U-shaped mounting bracket formed with aligned openings is disposed on each end of each one of a pair of chassis sideframes. Each clevis assembly is engageable with a respective one of the U-shaped brackets so that the respective openings of the engaged brackets are aligned. The pear-shaped openings allow vertical articulation of the chassis relative to the seat in certain instances when a bump, depression or other irregularity on a travel surface is encountered by usually one of the wheels of the wheelchair. |
