Description

Technical Field

[0001] The invention belongs to the technical field of automotive seat belt fixing point tests, and particularly relates to a split-type universal B-pillar device for tests. Background Art

[0002] With the research and popularization of vehicle safety projects, as one of the most important installation devices in vehicles, the improvement of the safety performance of seat belts has always been the focus of research and development personnel. Now, large automobile factories have developed and used seat belts with EBSS (lower fixing point pretensioning device), and a new seat belt static detonation test has been added for this seat belt.

[0003] The automotive B-pillar is a vertical beam on the vehicle, located between the front and rear seats of the cockpit, extending from the roof to the bottom of the vehicle. Since the door locks of the front and rear doors are installed on the B-pillar, and the entire door is supported by three points: the door lock, the upper hinge, and the lower hinge, seat belts, airbags, wires, and wire harnesses for the front row seats are provided on the B-pillar.

[0004] CN215677575U discloses a universal test fixture for seat belt static detonation tests, including a seat belt fixing mechanism, a seat fixture, and a fixture cart. The seat belt fixing mechanism and the seat fixture are both fixed on the fixture cart. The seat belt is installed on the seat belt fixing mechanism, and the seat belt fixing mechanism is provided with an upper seat belt fixing point installation and adjustment mechanism and a lower seat belt fixing point installation and adjustment mechanism; the seat belt fixing mechanism includes a mounting seat, a B-pillar imitation, an upper seat belt fixing point installation and adjustment mechanism, and a lower seat belt fixing point installation and adjustment mechanism; the B-pillar imitation is fixed on the mounting seat by bolts; the upper seat belt fixing point installation and adjustment mechanism is fixed on the top of the B-pillar imitation; the lower seat belt fixing point installation and adjustment mechanism includes a lower seat belt fixing point height adjustment mechanism and a lower seat belt fixing point angle adjustment mechanism. The lower seat belt fixing point height adjustment mechanism is fixed on the mounting seat, and the lower seat belt fixing point angle adjustment mechanism is fixed on the bottom of the B-pillar imitation.
