Description

Technical Field

[0002] In existing automobile zero-gravity seats, a rapid return mechanism is usually installed on the seat cushion and the backrest, so that after a collision occurs to the seat in a zero-gravity posture, through the rapid return mechanism, the seat can return to a proper backrest angle and / or seat cushion angle according to a predetermined route, so as to optimize the sitting posture to improve the restraint protection for the occupant (CN 117565761 A discloses the working principle and specific structure of the seat cushion rapid return mechanism). At present, when conducting a verification test in the development stage of the rapid return mechanism of the automobile zero-gravity seat cushion, in order to more truly reflect the verification accuracy of the mechanism, it is necessary to conduct the test at the actual installation position. Since the rapid return mechanism is a part of the seat frame assembly and more than 90% of the tests are strength tests, if the seat frame assembly is used for the test, the tested samples cannot be reused, so the verification test will consume a large amount of seat frame assemblies, increasing the development cost; in addition, some test standards require adding a constant torque to the seat cushion, and it is relatively difficult to achieve such a test condition on the frame.
