[0053] figure 1 It is an explanatory diagram showing a passenger car 1 equipped with an occupant protection device 10 according to the first embodiment of the present invention. The passenger car 1 is a multi-person car in which a driver and a passenger can ride. A car is an example of a vehicle. Below, with figure 1 The vehicle is used as a benchmark, use front and rear, left and right, up and down.

[0054] figure 1 The passenger car 1 has a body 2 . figure 1The vehicle body 2 is made of front part, middle part and rear part. Tires 3 are arranged at the front and rear of the vehicle body 2 .

[0055] In the middle of the vehicle body 2 is formed a seating space 4 in which the occupant M sits. In the passenger space 4, the seats 5 on which the driver or a passenger sits are arranged in front and rear rows. The seating space 4 has, for example, a frame structure in which a plurality of frame members are combined into a box-shaped frame. With this skeleton structure, t...

Abstract

A controller of an occupant protection device identifies the positions of the lower legs of an occupant seated in a seat based on detection signals of sensor modules, and controls the expansion states of airbag modules for lower legs as to the identified positions of the lower legs to support the lower legs of the occupant in the identified positions of the lower legs using the expanded airbag modules for lower legs.

Description

technical field [0001] The present invention relates to an occupant protection device for protecting occupants in vehicles such as automobiles. Background technique [0002] Seat belt modules and airbag modules are used in occupant protection devices (Patent Documents 1 and 2). [0003] The seat belt assembly is used to restrain an occupant sitting on a seat of a vehicle to the seat. [0004] The airbag module is used to deploy the airbag between a structure such as a steering wheel, an instrument panel, and a side panel of a vehicle and an occupant so that the occupant's upper body, such as the head, does not strongly hit the structure.
