Problems solved by technology
[0005] However, due to the characteristics of poor material quality such as unstable elastic density characteristics of different batches of raw materials and excessive local hardness deviation, the elastic foam sponge material will affect the use sensitivity of such seat body pressure switch products.
At the same time, due to the long-term pressure use of the elastic foam sponge material in the car, irreversible shape deformation and elastic modulus changes often occur, which will also affect the normal pressure activation state of the sensing contact of the pressure switch element. Even cause the application function of the product to fail

The invention discloses a human body pressure switch. The human body pressure switch comprises a pressure switch element and an elastic touch press body arranged at the upper side or lower side of the pressure switch element, the elastic touch press body comprises an interval support structure and a support force protrusion, the support force protrusion corresponds to a sensing touch point of the pressure switch element, in the state of external force pressure, the deformation amount of the interval support structure is larger than that of the support force protrusion, and in the state of no external force pressure, the interval support structure has the support effect. According to the human body pressure switch, in the state that no one sits at a seat, through the support effect of the interval support structure, the sensing touch point of the pressure switch element is prevented from being influenced by prepressing acting force like stress in a sponge structure of the seat itself and the sponge seat cushion weight. The invention further discloses a vehicle seat.
Description
technical field [0001] The invention relates to the technical field of car seats, in particular to a human body pressure switch and a car seat. Background technique [0002] With the development of science and technology in the field of vehicle transportation, seat occupancy monitoring, as an application requirement in the field of occupant seat belt reminder, has received more and more attention from the market. The pressure switch element is used to detect the presence of human body pressure from the seat surface through the seat, which can effectively sense the presence of the seat user and realize the function of user presence detection. [0003] A simple application of this type of seat body pressure switch product is to arrange a foil-type switch element and a matching structure between the load-bearing frame inside the vehicle seat and the foam pad of the seat cushion. When the pressure of the human body's buttocks acts on the seat surface of the seat sponge bearing ...
