Safety belt limiting test device under vertical environment

Abstract

The invention relates to the field of the seat safety belt performance test, specifically a test device of safety belt limiting under the vertical environment. The device comprises an experiment tablesystem, a seat dummy system and a test record system; the seat dummy system comprises a seat skeleton and an experiment dummy; a safety belt system is arranged on the seat skeleton, and the experiment dummy is fixed on the seat through the safety belt system. The experiment table system fixes the experiment seat skeleton dummy on the corresponding rack; the experiment table system releases the dummy seat system after hoisting the dummy seat system to a corresponding location, and test record system records all experimental data, thereby realizing the testing of the safety belt limiting through analysis data and experiment. The displacement feature of the passenger under a bottom explosion environment can be simulated through the test device of the passenger limiting under the vertical environment, the feasibility of the passenger limiting research under the bottom explosion condition is improved, the test stability is improved, the repeatability of the test device is good and the costis greatly reduced.

Description

technical field [0001] The invention relates to the field of occupant restraint systems in a vertical environment, in particular to a test device for occupant restraint in a vertical environment. Background technique [0002] In an explosive environment, the vertical limit of the seat belt directly affects the living space of the occupant, the severity of the occupant's injury, and even affects the survival rate of the occupant. [0003] Among the existing test methods for seat belts, most of them use chemical and physical methods for chemical substance structure analysis and tensile testing, etc., but this method cannot test the limitability of seat belts during actual use. And in the prior art, there are also people who have begun to test the restraint of the seat belt in the collision, but the restraint of the seat belt mainly focuses on the front and rear restraint of the seat belt. [0004] However, in various wars and terrorist incidents, if the bottom impact is encou...
