Adjustable occupant restraint system crash test device

Abstract

The invention discloses an adjustable occupant restraint system collision test device, which can perform restraint system parameter matching in allusion to different vehicle models and occupants with different physical characteristics and perform verification on matching parameters through a trolley collision test. The adjustable occupant restraint system collision test device comprises a steering wheel multi-directional comprehensive adjustment mechanism (1), a safety belt multi-directional comprehensive adjustment mechanism (2), a rigidity test seat multi-directional comprehensive adjustment mechanism (3) and a collision test trolley (61), wherein the safety belt multi-directional adjustment mechanism (2) comprises a safety belt upper fixing point adjustment mechanism (20), a safety belt lower fixing point adjustment mechanism (23) and a retractor adjustment mechanism (19), the rigidity test seat multi-directional comprehensive adjustment mechanism (3) comprises a seat backrest angle adjustment mechanism (4), a seat front-back adjustment mechanism (5), a seat cushion angle adjustment mechanism (6) and a seat height adjustment mechanism (7). The adjustable occupant restraint system collision test device can adjust the position of a steering wheel, a safety belt and a seat conveniently, and is simple in structure and low in cost.

Description

technical field [0001] The invention mainly relates to an occupant safety testing device, in particular to a test device for safety research, test and inspection of an automobile occupant restraint system. Background technique [0002] With the advancement of automobile safety technology and the improvement of people's safety awareness, the collision safety of automobiles has been paid more and more attention. When a car collides, at first the car collides with an external obstacle. Then, under the action of inertial force, the passenger will have a secondary collision with the car interior. The occupant restraint system can significantly reduce the risk of occupant secondary collision, thus effectively protecting the occupant's personal safety. Therefore, it is extremely important to design a reasonable restraint system to improve vehicle safety. [0003] In order to ensure that different occupants can get the best protection in the event of a vehicle collision, it is nec...

Problems solved by technology

Due to the limited adjustment range of these devices, it is only possible to study the movement and injury of the occupant under the matching of a single specific restraint system parameter, and it cannot comprehensively reflect the influence of each adjustment parameter while matching the occupant's physical sign parameters on the test results, which is not in line with the actual vehicle development. Considering various factors comprehensively in the process to achieve the optimal matching of the parameters of each constraint system
