Vehicle seat, vehicle seat control system and vehicle

Abstract

The disclosure relates to a vehicle seat, a vehicle seat control system and a vehicle. The vehicle seat includes a seat back and a headrest arranged above the seat back. The vehicle seat further includes a fixing part, and a crank arranged on the fixing part Slider mechanism, and the driving member used to drive the slider in the crank-slider mechanism to move up and down, the headrest is connected to the crank or connecting rod in the crank-slider mechanism, and the up-and-down movement of the slider can be converted into a crank or connecting rod to drive the headrest to move back and forth at the same height. When a rear-end collision occurs, the driving part drives the headrest to move forward automatically, adjusts the distance between the headrest and the occupant's head, supports the occupant's head, and avoids severe whiplash injuries to the occupant's neck. When the danger signal is released Finally, the headrest can be returned to its original position under the drive of the driving part or under the action of its own gravity and the occupant's head on the headrest. The headrest moves back and forth at the same height, which can ensure effective support for the occupant's head.

Description

technical field [0001] The present disclosure relates to the field of body interior decoration, in particular, to a vehicle seat, a vehicle seat control system and a vehicle. Background technique [0002] In modern times, car rear-end collision accidents caused by traffic congestion and other factors occur frequently. Due to the large distance between the headrest and the occupant's head, the occupant's head has no effective support when the accident occurs, causing the neck to bend excessively and causing whiplash injuries. . In the prior art, in order to avoid injury to the occupant's neck in a rear-end collision, the head restraint is usually designed as an active head restraint, such as a mechanical trigger active head restraint, an airbag active head restraint and a signal control active head restraint, After a rear-end collision occurs, the mechanical trigger headrest triggers the mechanical link device on the seat back under the inertia of the human body, driving the...

Problems solved by technology

[0002] In modern times, car rear-end collision accidents caused by traffic congestion and other factors occur frequently. Due to the large distance between the headrest and the occupant's head, the occupant's head has no effective support when the accident occurs, causing the neck to bend excessively and causing whiplash injuries.

In the prior art, in order to avoid injury to the occupant's neck in a rear-end collision, the head restraint is usually designed as an active head restraint, such as a mechanical trigger active head restraint, an airbag active head restraint and a signal control active head restraint, After a rear-end collision occurs, the mechanical trigger headrest triggers the mechanical link device on the seat back under the inertia of the human body, driving the headrest to move forward. The injury may have already been caused, and the trigger sensitivity of the headrest structure is low; the airbag-type active headrest is mainly provided with a headrest airbag between its fixed part and the movable part. Although the sensitivity of the airbag-type active headrest has been improved, the structure is complex and the detonation stability is poor; the signal-controlled active headrest has a certain prediction for rear-end collision accidents, and the movement of the motor is controlled before the rear-end collision occurs. The pillow is moved forward to avoid the occupant's neck injury to a certain extent, but the structure is complicated, and it is installed inside the headrest with a small space. The designability is low and the overall structure is affected.
