Problems solved by technology

The disadvantage of this method is that the shape of the cutout cannot be controlled after the energy absorbing device shrinks and deforms, and there is a risk that the screw head will be cut off by the edge of the cutout, resulting in failure of the vehicle seat structure after deformation
Moreover, the size, quantity and setting position of each component of the energy-absorbing device need to be accurately calculated and tested, which is difficult to control

Abstract

The invention discloses a vehicle seat, an energy absorption device thereof and a vehicle comprising the vehicle seat. The energy absorption device comprises a device body and a deformable absorptionpart, and the absorption part protrudes or is sunken relative to the device body. The vehicle seat is provided with the energy absorption device. The vehicle is provided with the vehicle seat. The energy absorption device is simple in structure and easy to implement, and the weight and the cost of the vehicle seat cannot be increased.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle seat. The invention also relates to an energy-absorbing device for a vehicle seat and a vehicle comprising the vehicle seat. Background technique [0002] Conventional vehicle seats generally include a seat back and a seat surface, and an adjustment device that adjusts the relative position of the seat back relative to the seat surface. For safety reasons, a deformable mechanism is also provided on the vehicle seat, which can collapse and deform in an accident to absorb energy, thereby ensuring that other components of the seat are not deformed, and reducing the impact on the occupants of the vehicle. [0003] WO2006003167A1 discloses a vehicle seat, the seat has a seat back and a seat surface and a seat adjustment device for adjusting the relative position between the two, the seat adjustment device is plate-shaped and has a notched Deformation mechanism in the form of a hole...
