Seat armrest and automobile seat

Abstract

The invention provides a seat armrest and an automobile seat. The seat armrest comprises an armrest framework, a rotation limiting mechanism and a return piece, wherein the armrest framework is rotationally connected with a seat backrest framework through a rotating piece; the rotation limiting mechanism can limit a rotation angle of the armrest framework; the rotation limiting mechanism comprises limiting teeth, which are arranged in a circumferential direction of the rotating piece, and a guide rod, which can rotate around the limiting teeth and is matched with a tooth groove of the limiting teeth; the return piece can drive the guide rod to be limited within the tooth groove when the armrest framework is rotated to a preset angle; and when the armrest framework is in rotating, the return piece can drive the guide rod to be separated from the tooth groove. According to the seat armrest, as the angle of the seat armrest is adjustable, the seat armrest can be adjusted to a comfortable angle according to a seat backrest at different angles and different use states of a passenger; therefore, the seat armrest can stay at an appropriate angle when the angle of the seat backrest is changed so as to ensure the taking comfort of the passenger.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a seat armrest, and also relates to an automobile seat. Background technique [0002] To improve occupant comfort, car seats are equipped with armrests on both sides to allow the occupant to rest their arms or elbows on the armrests. At present, the seat armrest installed on the car seat back frame can only stay in two positions, that is, the use position (horizontal position) and the stowed position (vertical upward or vertical downward). [0003] However, as the seat back is tilted forward or backward, the angle of the armrest connected to the backrest frame will also change accordingly, seriously affecting the driving comfort of the occupant. [0004] In addition, when the above-mentioned seat armrest is changed between two positions, only one damping sheet is used to ensure the position of the armrest; as the use time increases, the damping effect will becom...

Problems solved by technology

[0003] However, as the seat back is tilted forward or backward, the angle of the armrest connected to the backrest frame will also change accordingly, seriously affecting the driving comfort of the occupant.

[0004] In addition, when the above-mentioned chair armrest is changed between two positions, only one damping sheet is used to ensure the position of the armrest; as the use time increases, the damping effect will become worse and worse, and the acceleration or braking during driving will All may lead to the change of the position of the armrest, affecting the stability of the position of the armrest of the seat
