Embodiment Construction

[0037] figure 1 is a structural schematic diagram of a seat device according to an embodiment of the present invention. This embodiment provides an anti-whiplash seat device 100, such as figure 1 As shown, the seat device 100 may generally include a seat back frame 10 and a force limiting member 20 . The seat back frame 10 is fixedly connected to the seat back of the vehicle, and configured to be rotatably connected to the seat cushion of the vehicle. One side of the force limiting member 20 is connected with the seat cushion, and the other side is connected with the seat back frame 10 . The force limiting member 20 is configured to limit the rotation of the seat back frame 10 relative to the seat cushion when the impact force received by the seat back is less than a threshold value; The connecting part of the seat back frame 10 is torn relative to other parts of the force limiting member 20, and the end of the torn part is still connected to other parts.

Abstract

The invention belongs to the field of vehicles and provides a whiplash injury prevention seat device and a vehicle. The seat device comprises a seat backrest frame, a seat cushion and force limiting components. The seat backrest frame is fixedly connected with a seat backrest of the vehicle and is provided with a seat cushion rotationally connected to the vehicle. One side of each force limiting component is connected with the seat cushion, and the other side of each force limiting component is connected with the seat backrest frame. The force limiting components limit rotation of the seat backrest frame relative to the seat cushion when collision force applied to the seat backrest is smaller than a threshold; when the collision force applied to the seat backrest is larger than or equal tothe threshold, connection portions of the force limiting components and the seat backrest frame are torn relative to other portions of the force limiting components, and tail ends of the torn portions are still connected with other portions. The whiplash injury prevention seat device is evident in passenger protecting effect.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an anti-whiplash seat device and a vehicle. Background technique [0002] When a rear-end collision occurs, the seat back of the vehicle will cause a certain degree of whiplash injury to the head, neck and back of the occupant, affecting the safety of the occupant. [0003] Seats currently used in vehicles mainly reduce whiplash damage caused by rear-end collisions by reducing the hardness of the seat back, optimizing the stiffness of the headrest and optimizing the strength of the headrest rod. [0004] However, the method in the prior art has played a protective role to a certain extent casually, but the protective effect is not obvious, and the occupant will still receive relatively large injuries when a rear-end collision occurs. Contents of the invention [0005] An object of the present invention is to provide a whiplash-resistant seat device with a significant protective effect....
