Document Type and Number:
WIPO Patent Application WO/2022/022325
Kind Code:
A1
Abstract:
A pneumatic identification apparatus for the body weight of a seat occupant. The apparatus comprises a control unit (1) and a sensing apparatus, wherein the sensing apparatus comprises a pneumatic sensing apparatus and an auxiliary sensing apparatus; the pneumatic sensing apparatus comprises at least one soft elastic hollow structure body (3) and a sensing unit; the soft elastic hollow structure body (3) is in communication with a first air pressure sensor (5), the first air pressure sensor (5) being configured to measure a first air pressure value Pa in the soft elastic hollow structure body (3); the control unit (1) is configured to compare the first air pressure value Pa with a standard set value and correspondingly output a body weight type; and the auxiliary sensing apparatus comprises a top pressure-bearing plate (15) and a bottom carrying plate (16) which are respectively mounted on two end faces of the soft elastic hollow structure body (3). The pneumatic identification apparatus can detect whether there is an occupant, and can also effectively detect the body type of the occupant, thereby providing assistance for improvements in the safety performance and a vehicle safety system, and providing a reliable foundation for the development of vehicle safety. Further provided is a pneumatic identification seat with the pneumatic identification apparatus.
