Abstract

The utility model discloses a headrest device of a wheel chair for the disabled. The device mainly comprises a headrest cushion, a headrest bracket, a bracket locking screw, a cross bar, a longitudinal bar, a connecting piece, a lock plunger and a plum blossom nut, wherein the U-shaped headrest cushion is fixedly connected with the U-shaped headrest bracket which is fixedly connected with the inner end of the cross bar; the cross bar is sleeved with the connecting piece movably; the upper end surface of the longitudinal bar is fixedly connected onto the bottom surface of a U-shaped clamping piece and the lower end of the longitudinal bar can be inserted in the wheel chair back. Since the connecting piece with the longitudinal bar, which is connected to the end of the headrest device, can be clamped on the cross bar movably and locked through the lock plunger, and the length of the cross bar can be adjusted conveniently, therefore, the headrest cushion position fixed at one end of the cross bar can be adjusted conveniently, which brings great convenience to the use of the disabled and more comfortable sitting feeling for the disabled.

Description

The Wheelchair head rest device no

Technical field

This utility model relates to a kind of Wheelchair, particularly relates to a kind of Wheelchair head rest device no.

Background technology
