Abstract

The invention relates to a pawl-type backrest multi-section lock that comprises the following parts: a lock support fixed on a backrest framework; a multi-section lock unit arranged on the lock support and provided with a turnable locking claw assembly, wherein at least one locking claw is arranged in the locking claw assembly; a plunger latch fixed on a vehicle body, wherein a plurality of plunger latch holes are formed in the plunger latch, the locking claws fall into different plunger latch holes, so that different angles of the backrest framework can be adjusted; and an unlocking mechanismthat drives the locking claw assembly to turn over, so that the locking claw is turned into or out of the plunger latch hole, and locking and unlocking between the locking claw assembly and the plunger latch are achieved. Multi-section adjustment of the backrest can be achieved, the angle adjusting range can reach 8.4 degrees, and therefore the requirements of more user groups for the comfort angle of the backrest are met.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a pawl-type backrest multi-segment lock. Background technique [0002] The seat of a vehicle includes a seat cushion as a seat surface and a seat back as a backrest, wherein the seat back can be positioned between an upright posture for normal riding and a flat posture that can be folded forward for convenience of loading. switch between pitches.
