Vehicle seat with adjustable headrest

Abstract

The invention relates to the technical field of seats, in particular to a vehicle seat with an adjustable headrest. The vehicle seat comprises a seat support and a headrest support connected with theseat support in a sliding mode. A first connecting plate and a second connecting plate are fixedly connected to the seat bracket; an adjusting limiting plate is connected between the first connectingplate and the second connecting plate, a clamping groove is formed in the adjusting limiting plate, the headrest support comprises a connecting base plate, a limiting clamping strip is connected to the connecting base plate, the limiting clamping strip comprises a bent part, and the bent part is arranged towards the adjusting limiting plate and extends into the clamping groove. In the sliding process of the seat headrest, the bent portion in the limiting clamping strip can be matched with the clamping groove in the adjusting limiting plate in a clamped mode, limiting clamping of the seat headrest is achieved, the bent portion of the limiting clamping strip is stable in shape and can extend into the clamping groove all the time, and therefore the positioning function of the headrest can beguaranteed, and the headrest can be normally adjusted and positioned after being used for a long time.

Description

technical field [0001] The invention relates to the technical field of vehicle seats, in particular to a vehicle seat with an adjustable headrest. Background technique [0002] The seats used on most existing vehicles include seat backs and headrests arranged above the seat backs. In order to improve people's comfort during use, the headrests on the seats can be adjusted so that the user can time can be more comfortable. [0003] In the prior art, the Chinese invention patent with the publication number CN109624811A specifically discloses a seat with a stepless adjustable headrest, which includes a seat frame, a headrest support frame, a guide rail, a slider, and a headrest body; , the headrest support frame is fixedly arranged on the upper part of the seat frame, and the guide rail is fixedly arranged on the headrest support frame; the headrest body is fixedly connected with the slider, and the slider and the guide rail are longitudinally slidable; and the slider is provid...

AI Technical Summary

Problems solved by technology

Although the above technical solution can realize the adjustment and positioning of the headrest, the elastic force of the abutting block and the elastic force of the elastic part need to be precisely controlled. If the elastic force is too large, it will affect the smoothness of the headrest adjustment. If the elastic force is too small, the head The pillow cannot realize the positioning clamping connection stably, and it is prone to loosening

And after the headrest has been used for a long time, the abutting block will be worn out, and the elastic force of the elastic parts will also become loose, so the headrest cannot be positioned, which will directly affect the use of the headrest
