According to the seat provided by the embodiment of the application, the second connecting piece and the first connecting piece can be fixed by arranging the locking part to penetrate through the second opening on the first connecting piece and the first opening on the second connecting piece, so that the headrest can rotate to a normal use position; set up the depression bar simultaneously and mutually support with the elastic component, can reduce the shared space of headrest with the headrest holding that the passenger did not use in the back portion of seat body to optimize passenger's the field of vision, be favorable to the change of passenger's timely reply road conditions.

The following describes in further detail a specific rotation manner of the headrest in the seat provided by the embodiment of the present application with reference to practical application scenarios and fig. 1, 2, 7 and 8.

For example, when a passenger needs a wide field of view to timely cope with a change in road conditions, the passenger may press down the pressing rod 34, and the pressing rod 34 acts on the elastic member 35, so that the elastic member 35 is in a compressed state; at the same time, the locking component 33 can move downward in the height direction of the seat body 1 in the guide slot hole 311, and is disengaged from the first opening 3211 and the second opening 3221. At this time, the passenger may manually rotate the headrest 2 toward the accommodation space 11 in the backrest portion of the seat body 1, that is, the second link 321 may rotate in the first link 322, so that the headrest is accommodated in the accommodation space 11. In the case that the passenger needs to use the seat headrest normally, the passenger can manually rotate the headrest, at this time, the elastic member 35 rebounds to push the locking member 33 to move upward in the height direction of the seat body 1 in the guide slot hole 311, and when the passenger rotates the headrest, that is, the second opening 3221 of the second connecting member 321 coincides with the first opening 3211, the locking member 33 can fix the position of the headrest by passing through the second opening 3221 and the first opening 3211 to fix the second connecting member 321 and the first connecting member 322; meanwhile, the protrusion 3212 may abut against the position-limiting portion 3222, so as to prevent the second connecting element 321 from rotating excessively relative to the first connecting element 322.

In this way, the second connecting piece and the first connecting piece can be fixed by arranging the locking part to penetrate through the second opening on the first connecting piece and the first opening on the second connecting piece of the fixing bracket, so that the headrest can be rotated to a normal use position; meanwhile, the pressing rod and the elastic piece are arranged to be matched with each other, so that a headrest which is not used by a passenger can be accommodated in the backrest part of the seat body, and the space occupied by the headrest is reduced, therefore, the visual field of the passenger is optimized, and the passenger can respond to the change of road conditions in time.

In one embodiment of the present application, the seat may be a front passenger seat. When the front-row passenger seat is occupied, the headrest of the passenger seat can be turned over and hidden, namely, the headrest is accommodated in the accommodating space. Therefore, a wide front visual field can be brought to the back row passengers, the back row copilot side visual field is basically the same as that of the front row, the back row passengers can always see the front road condition, and the back row passenger cabin side visual field is favorable for timely making a proper response to deal with the change of the road condition, so that the back row passenger cabin side visual field is favorable for riding safety and is not easy to carsickness for people; meanwhile, the driver can have better lateral and backward vision after the headrest is folded.

Since the passenger seat on the rear-row side is more and more important, the passenger seat on the front-row side can be more comfortable when seated by hiding the headrest of the passenger seat on the front-row side. Meanwhile, in the case of vehicle collision or emergency braking, when a rear passenger collides with the backrest of the seat, the surface of the headrest is entirely made of soft material, so that the injury to people can be reduced. In addition, the headrest and the whole seat are integrated, so that the seat headrest does not need to be independently installed in a final assembly workshop for producing the seat, and the final assembly process is saved; also, the headrest may be folded in the backrest of the seat, so that the space in the vehicle and the management, storage, and transportation costs may be saved.

This application utilizes the vacant region in back of the seat back to set up to the accommodation space of headrest, hides the seat headrest into, has not only opened the back row field of vision to the front seat after the deformation can play better guard action to the back row passenger.
