Description

Headrest and folding seat with buckle function Technical Field The application relates to the technical field of seat structures, in particular to a headrest with a buckling function and a folding seat. Background The headrest of the seat is a comfort configuration article on the seat, is arranged at the top of the backrest part of the seat, and can support the head of a sitting user in the use process of the user, thereby providing comfortable sitting feeling for the user. In the conventional folding seat, a backrest portion of the seat can be unfolded and folded with respect to a seat surface portion of the seat. Therefore, when the seat is folded, the headrest needs to be folded. In the existing folding seat, a headrest is turned over and then clamped between a folded backrest part and a seat surface part, so that the folding function of the seat is realized. After some seats are folded, locking force is applied only through a damping structure at the hinge part, so that the backrest part and the seat surface part are kept in a folded state. However, for some portable folding seats, there is a need for use in some convenient-to-carry applications, such as outdoors and the like. In the process of carrying and carrying the seat, the resistance of the damping structure is insufficient, and the backrest part and the seat part which are limited only by the damping structure are easy to open, so that the problem of inconvenient use is caused. Accordingly, the prior art is still in need of improvement and development. Disclosure of utility model In view of the above-mentioned shortcomings of the prior art, an object of the present application is to provide a headrest and a folding seat with a buckle function, which solve the problem that the folded backrest and seat surface are easy to open when some folding seats in the prior art are moved.
