Problems solved by technology

However, the height of the headrest is currently adjustable manually. If the occupant is short, or the headrest is at the highest limit position, or the backrest is tilted back, causing the passenger to lie on his back, there will be a head protection blind spot at this time, and a collision will occur. There is a risk of head entrapment when this occurs

Abstract

The invention provides an automobile seat. The automobile seat comprises a head cushion and a backrest which are configured in a matched manner, wherein the head cushion is connected with the backrest through a head cushion rod, and comprises a head cushion movement mechanism; the head cushion movement mechanism comprises an operation force generating assembly and a movement assembly; the movement assembly comprises a limiting buckle clamping shaft, a movable board and a pull force spring; a clamping shaft through hole is formed in the movable board; the limiting buckle clamping shaft is fixedly connected with the movable board through the clamping shaft through hole; one end of the pull force spring is connected with the movable board; the movable board is further connected with the head cushion rod; the other end of the pull force spring is connected with the backrest. According to the automobile seat, the operation force generating assembly and the movement assembly are configured in the matched manner, so that the height of the head cushion, which is relative to the backrest, is automatically and rapidly realized. Therefore, the damage that the head of a passenger is clamped in the connection of the head cushion and the backrest can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of safety equipment used in automobiles, in particular to an automobile seat. Background technique [0002] When the vehicle has an emergency braking situation, the headrest of the high-end seat at this time generally uses the headrest to actively protect the passenger. The principle is to rely on the passenger to squeeze the backrest, so that the headrest moves forward in advance, thereby shortening the head. This is an ideal state to reduce the deformation of the neck and protect the passengers. However, the height of the headrest is currently adjustable manually. If the occupant is short, or the headrest is at the highest limit position, or the backrest is tilted back, causing the passenger to lie on his back, there will be a head protection blind spot at this time, and a collision will occur. There is a risk of head entrapment when this occurs. Contents of the invention [0003] In view of this, the ...
