Vehicle body structure for preventing automobile seat from sinking

Abstract

The invention discloses a vehicle body structure for preventing an automobile seat from sinking. The main body section of the vehicle body structure is omega-shaped; the omega-shaped vehicle body structure comprises a front flange (2) and a back flange (3) connected with a vehicle back floor (1); the front flange (2) and the back flange (3) extend upwards to form oblique planes on both sides respectively; the top ends of the oblique planes on both sides are connected together; the front oblique plane consists of a front right side oblique plane (4) and a front left side oblique plane (5); the back oblique plane (6) is an entire plane. According to the vehicle body structure for preventing the automobile seat from sinking with the structure, the omega-shaped main body section is formed, and the vehicle body structure is directly connected with the vehicle back floor by spot welding without extra installation; during collision of real vehicles, back row passengers are prevented from sinking and being deviated, the system restraining effect is enhanced, and injury to back row passengers is reduced.

Description

technical field [0001] The invention relates to a vehicle body floor assembly, in particular to a vehicle body structure for preventing car seats from submerging. Background technique [0002] GB11551-2003 "Occupant Protection in Frontal Collision of Passenger Cars" only examines the injuries of the front row occupants, and fails to consider the injuries of the rear row dummy, but the 2012 version of the C-NCAP management rules increases the damage value of the rear row dummy Inspection, increased the requirements for the injury limit of the back row dummies. The rear floor design of similar models only considers the issue of seat installation, and the rear floor is designed as a flat structure. In the actual collision process, the rear occupants have the phenomenon that the pelvis slips out of the seat, which cannot prevent the rear occupants from diving. The role of seat belts in the collision process is reduced, and this type of occupant movement posture is not conducive...

The rear floor design of similar models only considers the issue of seat installation, and the rear floor is designed as a flat structure. In the actual collision process, the rear occupants have the phenomenon that the pelvis slips out of the seat, which cannot prevent the rear occupants from diving. The role of the seat belt in the collision process is reduced, and the occupant's movement posture is not conducive to the protection of the occupant by the restraint system, increasing the injury to the occupant
