Title:
ROTATABLE AND LENGTH-ADJUSTABLE MULTIDIRECTIONAL SHOCK ABSORBING BREATHING APPARATUS BEARING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/218059
Kind Code:
A1
Abstract:
A rotatable and length-adjustable multidirectional shock absorbing breathing apparatus bearing device, comprising: a back plate (1), the back plate being provided with a slot (6); a fastener (2), movably placed in the slot; a bearing device (3), the bearing device being connected to the fastener and fixed to the back plate; shock absorbers (4), provided on one side of the bearing device; and lumbar support plates (5), provided on the shock absorbers and used for reducing the shock of the lumbar support plates by means of the shock absorbers. The breathing apparatus bearing device uses a shock absorbing and rotating device to better fit the curve of a human body; due to the design of the lumbar support plates and a left-right two-piece type structure, the impact force on the human body generated by relative displacement of the breathing apparatus and the human body is reduced during operation; and the rotatable bearing device can better adapt to the change of the curve of the human body, and also avoid the direct pressing between the spine and the back plate when the human body bends, thereby achieving the objectives of shock absorption and buffering.
