Embodiment Construction

[0052] The occupant protection device 10 for a vehicle as the occupant protection device according to the first embodiment of the present invention will be based on Figure 1A to Figure 7B Be explained. It should be noted that arrows FR, UP, IN, and OUT appropriately drawn in the respective figures indicate the forward direction (traveling direction) of the automobile to which the vehicle occupant protection device 10 is applied, the upward direction thereof, and the direction in the vehicle width direction. inward direction and outward direction in the vehicle width direction. These arrows substantially coincide with the forward direction of the vehicle seat 11 to which the vehicle occupant protection device 10 is applied, its upward direction, one side in the seat width direction, and the other side in the seat width direction, respectively.

[0053] figure 2 It is a partially cutaway side view showing a state where the vehicle occupant protection device 10 applied to the...

Abstract

A vehicular occupant protection apparatus (10) is equipped with a seatbelt (12) including a shoulder belt portion (12A) fitted to a occupant (P) from a shoulder part thereof to a lumbar part thereof, a pretensioner mechanism (24) that is actuated to remove slack in the seatbelt (12), a force limiter mechanism (26) for limiting a restraint load applied to the occupant by the seatbelt (12), an air belt device (44) that supplies an air belt (45) with gas to inflate / deploy the air belt (45) between the occupant (P) and an instrument panel, and a occupant protection ECU (55) that actuates the air belt device (44) such that the air belt (45) starts being supplied with gas upon or after start of actuation of the force limiter mechanism (26) following actuation of the pretensioner mechanism (24) in the event of a head-on collision of a vehicle.

Description

technical field [0001] The present invention relates to an occupant protection device for protecting an occupant of a vehicle, and a control method for the occupant protection device. Background technique [0002] There is known a technology used as a power limiter (for example, see Japanese Laid-Open Document of PCT Application: Publication No. 11-508514 (JP-A-11-508514)), in which an air bag is deployed in the event of a vehicle collision The force limiter then allows the seat belt to be withdrawn while limiting the restraint load (absorbed energy) exerted by the seat belt. Furthermore, there is known a technology in which a seat belt is provided with an inflated portion for a head-on collision (for example, see Japanese Patent Application (JP-A-63-258239) with publication number 63-258239 and publication number 2005-297917 Japanese Patent Application (JP-A-2005-297917)). In addition, a technique is known in which gas inflatable seat belts are respectively provided with ...
