Abstract

The application discloses a buffer seat and a vehicle, and relates to the technical field of vehicle seats. The buffer seat comprises a seat body, a front supporting piece, a rear supporting piece and a damping component, wherein the first end of the front supporting piece is fixedly connected to the front end of the seat body, the second end of the front supporting piece can rotate relative to the vehicle body around a first axis, the first end of the rear supporting piece is rotatably arranged at the rear end of the seat body around a second axis, the first axis and the second axis are parallel and extend along the left and right directions of the vehicle body, the damping component is arranged on the vehicle body, the second end of the rear supporting piece can be limited, and the limitation is released when the inertial sliding block moves forwards relative to the vehicle body, so that the seat body can be rotated backwards around the first axis. The application can solve the potential safety hazard of severe collision with the steering wheel or the instrument panel caused by inertia forward-rushing of drivers and passengers when the existing automobile seat is braked or collided emergently, and particularly avoids the problem of failure of the protection function caused by power failure depending on an electronic control system.

Description

Buffer seat and vehicle Technical Field The invention belongs to the technical field of vehicle seats, and particularly relates to a buffer seat and a vehicle. Background In the process of continuous development of the automobile industry, the automobile seat is taken as an important component part in the automobile, the performance and the design of the automobile seat are directly related to the safety of drivers and passengers, and various road conditions, such as emergency braking, are inevitably encountered in the running process of the automobile. When an automobile encounters emergency braking, a driver can suddenly tilt forward under the action of inertia, and aiming at the potential safety hazard, the protection design of the existing automobile seat has a certain limit. While some vehicle types are equipped with safety airbags, severe collision between the body and the parts such as a steering wheel, an instrument panel and the like is still difficult to completely avoid or effectively reduce, and other vehicle types adopt a sensor linkage motor electric control system to attempt to buffer impact force through active tilting and overturning of a seat.
