Seat

Abstract

The invention provides a seat, relates to the technical field of vehicle inner decorations, and aims at solving the problem that a car seat is easy to tear in the prior art. The seat comprises a seatpedestal and a seat back, wherein the seat pedestal is provided with a first mounting hole, the seat back is provided with a second mounting hole, and a fixing part passes through the first mounting hole and the second mounting hole so as to connect the seat back with the seat pedestal; the seat pedestal is provided with multiple first clamping teeth, and the multiple first clamping teeth are arranged at intervals on the periphery of the first mounting hole; the seat back is provided with multiple second clamping grooves, the number of the second clamping grooves is equal to the number of thefirst clamping teeth, and the first clamping teeth can stretch into corresponding second clamping grooves. The seat is applied to public transportation vehicles, the seat pedestal and the seat back are further clamped in a coordinated mode through the first clamping teeth and the second clamping grooves except being connected by a fixing part, the connecting region is relatively great, and external force disperses in the process of external force tearing, so that damage caused by the external force to the seat is reduced or even avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle interior decoration, in particular to a seat. Background technique [0002] At present, the seat back and the seat seat of the seat of a public transport vehicle are usually a hollow structure of integral injection molding. When the vehicle brakes, the passenger sitting on the seat will lean back under the action of inertia, and the seat Passengers on the rear side will hold the back of the seat and pull the back of the seat backward under the action of inertia. Torn with the seat seat. [0003] In addition, there is also a seat in the prior art, the seat back and the two sides of the seat seat are connected by screws. When the vehicle brakes, the seat back is stressed, and the external force is concentrated on the screw connection, so that the screws are connected to the seat back or the seat back. There is looseness between the threaded holes on the seat, and the back of the chair is easy to l...

Problems solved by technology

[0002] At present, the seat back and the seat seat of the seat of a public transport vehicle are usually a hollow structure of integral injection molding. When the vehicle brakes, the passenger sitting on the seat will lean back under the action of inertia, and the seat Passengers on the rear side will hold the back of the seat and pull the back of the seat backward under the action of inertia. tear with the seat

[0003] In addition, there is also a seat in the prior art, the seat back and the two sides of the seat seat are connected by screws. When the vehicle brakes, the seat back is stressed, and the external force is concentrated on the screw connection, so that the screws are connected to the seat back or the seat back. There is looseness between the threaded holes on the seat, and the back of the chair is easy to loosen or even tear with the seat
