Embodiment Construction

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] 1. Static strength test of seat assembly and strength test of seat back and its adjustment device

[0059] 1) Static strength test of seat assembly In this specific embodiment, the test seat (67) is adjusted to a good position, and the seat (67) is fixed on the seat fixing platform (3) with bolts. Adjust the upper and lower position adjustment plate (14) of the beam and the left and right position adjustment plate (16) of the hydraulic cylinder, and at the same time turn the angle adjustment rocker (11) of the hydraulic cylinder so that the center line of the hydraulic cylinder 1 (23) passes through the seat (67) Center of mass, seat (67) and hydraulic cylinder (23) are connected by steel cable then. A pressure sensor (20) is installed at the front end of the hydraulic cylinder 1 (23), and the control system controls the hydra...

Abstract

The invention discloses a test device for a comprehensive test of an occupant restraint system. The device can carry out a seat assembly static strength test, a strength test for a backrest and its adjusting equipment, a headrest performance test and an automobile safety belt fixed point strength test according to the requirements of laws and regulations. The test device mainly comprises three modules, i.e. a test bench, a hydraulic system and a measurement and control system. The test bench consists of a main test bench, a seat fixation platform, a safety belt fixation column and a headrest impact test bench that function as load bearing parts during an experiment; the hydraulic system consists of a motor, a hydraulic pump, hydraulic control valves and a hydraulic cylinder etc. that serve as power output parts during an experiment; the measurement and control system includes a host computer, a data collection card, sensors and LabVIEW engineering software that serve as parts for datacontrol and recording during an experiment. The device of the invention has the characteristics of simple structure, low cost, convenient operation and multiple test functions etc.

Description

technical field [0001] The invention mainly relates to the field of comprehensive testing of automobile occupant restraint systems, in particular to a test device for performance testing of automobile seats, automobile seat headrests and automobile safety belts. Background technique [0002] The occupant restraint system is one of the most important passive safety devices in automobiles, and its reliability is even related to the life safety of occupants in collision accidents. 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 function of the car occupant restraint system is to restrain the occupant in the sitting position, reduce the risk of collision between the occupant and the interior of the car, thereby reducing the injury suffered by the occupant in the accident. Therefore, the optimization and reliability of occupant restraint s...
