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.
Claims19
An occupant protection device comprising:
- one or more airbag modules comprising a lower leg airbag module having a lower leg airbag that expands toward at least one lower leg of an occupant seated in a seat of a vehicle;
- a controller that controls the lower leg airbag module;
- and
- one or more sensor modules comprising an occupant sensor module that includes a sensor that detects the occupant seated in the seat, wherein
- the lower leg airbag has a stored state and an expanded state, the expanded state of the lower leg airbag being variable via the controller, and
- the controller is connected with the occupant sensor module and identifies a position of at least one lower leg of the occupant seated in the seat based on a detection signal of the occupant sensor module, and controls the expanded state of the lower leg airbag to correspond with the identified position to support at least one lower leg of the occupant in the identified position.
3 more elements
An occupant protection device comprising:
- one or more airbag modules comprising at least two lower leg airbags that expand toward at least one lower leg of an occupant seated in a seat of a vehicle;
- a controller that controls the lower leg airbags;
- and
- one or more sensor modules comprising an occupant sensor module that includes a sensor that detects the occupant seated in the seat, wherein
- the lower leg airbags have stored states and expanded states, and
- the controller is connected with the occupant sensor module and identifies a position of at least one lower leg of the occupant seated in the seat based on a detection signal of the sensor, and controls one of the two lower leg airbags to expand to the expanded state to correspond with the identified position of at least one lower leg of the occupant, and controls the other of the two lower leg airbags to remain in the stored state.

An occupant protection device comprising:
- one or more airbag modules comprising at least two lower leg airbags that expand toward at least one lower leg of an occupant seated in a seat of a vehicle;
- a controller that controls the lower leg airbags;
- and
- one or more sensor modules comprising an occupant sensor module that includes a sensor that detects the occupant seated in the seat, wherein
- the lower leg airbags have stored states and expanded states,
- the controller is connected with the occupant sensor module and identifies a position of at least one lower leg of the occupant seated in the seat based on a detection signal of the sensor, and controls the two lower leg airbags to expand both airbags to the expanded states to correspond with the identified position of at least one lower leg of the occupant,
- the controller controls the two lower leg airbags to expand with offset timings.
