Embodiment Construction

[0029] The embodiment of the seat occupancy sensor and the car seat thereof of the present invention will be described in detail below with reference to the accompanying drawings, wherein the same or similar elements or parts in each embodiment use the same reference numerals.

[0030] In one embodiment of the present invention, a car seat includes a bottom support part and a seat cushion, and the seat cushion is arranged on the bottom support part. The seat cushion is for the occupant to ride on, and can be made of soft material, and can be a commonly used seat cushion in this field, such as a sponge foam cushion. It is easy to understand that in the embodiment of the present invention, the car seat may further include a rear support portion for the occupant to lean on.

[0031] In an embodiment of the present invention, the car seat may further include at least one seat occupancy sensor disposed between the seat cushion and the bottom support.

[0032] The structure of the ...

Abstract

The embodiment of the invention discloses a seat occupation sensor. The seat occupation sensor comprises a load-bearing plate with a pressure transformation characteristic, at least one flexible pressure activated layer and a pressure switch element, wherein the load-bearing plate with the pressure transformation characteristic, the at least one flexible pressure activated layer and the pressure switch element are laminated with one another, and the at least one flexible pressure activated layer is next to the pressure switch element. The seat occupation sensor is not needed to be arranged on a bearing surface of a cushion of the automobile seat, but can be arranged between a bottom supporting part and a cushion of the automobile seat, so that the anti-loss performance of the seat occupation sensor is increased, the problem of frequent breakdown of various passenger detection sensing parts at present can be effectively solved, and the effective detection area of the surface of the seat is increased.

Description

technical field [0001] The invention relates to the technical field of occupant identification of car seats, in particular to a seat occupancy sensor and a car seat thereof. Background technique [0002] In recent years, the active and passive safety technology of automobiles has been greatly developed. From the perspective of occupant driving safety protection, the requirements of vehicles for the detectability of occupant occupancy are also increasingly strengthened. During the driving process of the vehicle, by detecting and judging the use of the passenger seat, it can not only remind the use of the seat belt, but also control the active pre-tensioning of the seat belt and the deployment of the airbag in the event of an accident. etc. to provide judgment. [0003] In the current application of the occupant human body occupancy sensing system, the pressure sensing device installed on the load-bearing surface of the passenger seat, that is, the inside of the cover on the ...
