Seat system with anti-diving airbag

Abstract

The invention discloses a seat system with an anti-diving airbag. A seat is mounted on a vehicle body in a slideable manner; the seat comprises a front half seat basin, a rear half seat basin, a backrest and supporting feet, wherein the front half seat basin, the rear half seat basin and the backrest can bear a human body, and the supporting feet are arranged at the bottom of the front half seat basin and at the bottom of the rear half seat basin and connected with the vehicle body in a slideable manner; the front half seat basin is pivotably connected with the rear half seat basin; a bracketand a supporting device are arranged on the supporting foot at the bottom of the rear half seat basin; the bracket is hinged to the rear half seat basin and supports the rear half seat basin; the supporting device supports the bracket and can receive a signal from an acceleration sensor in the vehicle body; and when the signal of the acceleration sensor exceeds a threshold, the supporting for thebracket is withdrawn and the rear half seat basin is enabled to sunk. According to the seat system with the anti-diving airbag, when a vehicle suffers a sudden accident, the gravity center of a passenger can be moved backwards to achieve the purpose of protecting the passenger to the most extent.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a seat system with an anti-submersion airbag. Background technique [0002] With the continuous improvement of automobile safety performance, there are more and more requirements for the design of vehicle seats, including the anti-submarine performance of seats. When the vehicle is subjected to a frontal collision or sudden braking, due to the sharp decrease in speed, the occupant's buttocks will move forward and downward due to inertia, that is, diving or slipping occurs. This may affect the normal functioning of restraint systems (such as seat belts, DAB, PAB, SAB, etc.), resulting in occupant injuries. In addition, if the seat pan of the seat is not strong enough, the force exerted by the occupant on the seat pan will cause a large deformation of the seat pan, so that the seat pan structure cannot provide sufficient support for the occupant, resulting in greater slip...
