Leg support structure for a car seat

Abstract

This utility model provides a leg support structure for a car seat. An air bag with adhesive backing is attached to the front end of a foam core. An inflation tube from the air bag is then inserted into a foam groove on the foam core, with one end of the inflation tube connected to the air bag. Soft foam is then attached to the foam core, and a cover is fitted over the foam core and soft foam. The seat frame is connected to a seat cushion spring, and the seat cushion assembly is connected to the frame assembly. The other end of the inflation tube from the air bag is connected to an air pump. Finally, the air pump is secured to the seat cushion spring. A wiring harness is electrically connected to an air pump switch, which is secured to a protective plate. The protective plate is then secured to the seat frame. A pneumatic device is added between the foam core and the soft foam. The air bag is connected to the foam core via adhesive backing. The air pump is mounted on the seat cushion spring on the seat frame to prevent compression. The driver controls the inflation and deflation of the air pump by adjusting the air pump switch. The inflation and deflation of the air pump can change the inflation volume of the air bag, thereby changing the leg support provided by the front end of the seat cushion for drivers and passengers of different body types.

Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and in particular relates to a leg support structure for an automotive seat. Background Technology

[0002] As living standards improve, people's pursuit of cars is no longer simply about transportation, but has evolved from single-function vehicles to personalized comfort needs.

[0003] From a usage perspective, during long drives, the back of the thighs can easily suffer from poor blood circulation (numbness, soreness) due to being unsupported or experiencing concentrated pressure. The extended front part of the seat cushion can support the thighs, reduce the weight on the buttocks, and distribute pressure. From a design perspective, the protruding front edge of the seat cushion enhances the seat's sporty look.

[0004] In summary, the demand for extended front end designs of car seats is on the rise, making front end support particularly important. Therefore, we urgently need to design a leg support structure for car seats to address these issues. Utility Model Content
