Vehicle seat, vehicle seat control system and vehicle

Abstract

The invention relates to a vehicle seat, a vehicle seat control system and a vehicle. The vehicle seat comprises a seat backrest and a headrest arranged above the seat backrest. The vehicle seat further comprises a fixing part, a slider-crank mechanism arranged on the fixing part, and a driving part used for driving a slider in the slider-crank mechanism to move up and down. The headrest is connected to a crank or a connecting rod in the slider-crank mechanism, and the up-down movement of the slider can be converted into the rotation of the crank or the connecting rod so as to drive the headrest to move back and forth at the same height. When rear-end collision accident occurs, the driving part drives the headrest to automatically move forwards. The distance between the headrest and the head of the passenger is adjusted, the head of the passenger is supported, serious whiplash injury to the neck of the passenger is avoided, and after a danger signal is removed, the headrest can returnunder the driving of the driving part or under the action of the gravity of the headrest and the head of the passenger on the headrest, so that the headrest returns to the initial position. The headrest moves back and forth at the same height, so that the head of a passenger can be effectively supported.

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.
