AI Technical Summary

Technical Problem

In existing technologies, redundant wiring harnesses in car seats are prone to accumulation during the backrest folding process, which affects mechanical stability and space utilization, increases the risk of interference with mechanical components, and is prone to insulation layer damage and internal copper wire breakage after long-term use.

Method used

Design a redundant length adaptive adjustment wire harness assembly. By setting a detachable tension spring connected to the moving section, the elastic deformation of the spring is used to maintain the orderly stacking state of the wire harness, and the detachable connection achieves the stability of the elastic coefficient, thus avoiding excessive stretching of the wire harness.

Benefits of technology

This design achieves stable and orderly stacking of redundant wire harness length during backrest folding, reducing the risk of interference with mechanical components, improving service life and seat aesthetics, and lowering the risk of wire harness breakage.

Abstract

The utility model discloses a wire harness assembly capable of adaptively adjusting redundant length and an automobile seat, the wire harness assembly comprises a connecting wire harness, and the connecting wire harness comprises a moving section with redundant length and a fixed section; the fixing piece comprises an extension spring, one end of the extension spring is fixed relative to the cushion and is detachably connected with the cushion, and the other end of the extension spring is detachably connected with the redundant length part and has the same motion state with the redundant length part. According to the utility model, the extension spring is connected with the redundant length part, so that when the backrest rotates relative to the cushion, the extension spring can maintain the tension between the moving section and the fixed section through the elastic deformation of the extension spring, thereby maintaining the orderly accumulation of the redundant length part and further stably maintaining the orderly accumulation state of the connecting wire harness; the two ends of the extension spring are detachably connected, so that the extension spring can be replaced at any time, the elastic coefficient of the extension spring connected with the moving section is stabilized all the time, and the redundant length part can stably keep an orderly stacking state for a long time.
