Abstract

PROBLEM TO BE SOLVED: To provide a side part structure for vehicle that secures a space for expanding an air bag between a slide door and a seat by outwardly moving a lock mechanism by a drive means when a side collision is predicted, thereby reliably expanding the air bag and allowing a large air bag to be mounted.SOLUTION: When a side collision is predicted by predicting input of a predetermined or larger load from the side, the drive means 59 is provided for moving the lock mechanism 52 to the outside of the vehicle to expand a bag part of a side air bag device in the space between the slide door 11 and the seat enlarged by moving the lock mechanism 52 to the outward.

Description

  The present invention relates to a side part structure of a vehicle including a side airbag device having a bag part that inflates and deploys between a seat and a sliding door at the time of a side collision of the vehicle.

In general, side airbags are deployed to protect the passenger from impact from the side when the vehicle collides, but in the event of a side collision, the passenger moves to the door trim side due to its inertial force. The space between the seat to be seated and the door trim was narrowed, and a sufficient space for deploying the side airbag could not be secured.
In order to solve such problems, a door device disclosed in Patent Document 1 has already been invented.

  The conventional structure disclosed in Patent Document 1 is provided with an extrusion mechanism having a piston and an inflator, and a plurality of extrusion mechanisms are interposed between the body and the door so that a side collision is predicted. When the piston of the side is moved to the outside of the vehicle and is held in this state, the entire front door is moved outward (so-called out), and the piston undergoes plastic compression deformation due to impact at the time of side collision. In order to prevent the front door from coming into contact with the occupant, the bag that can expand the space between the front door and the seat is inflated and deployed to protect the occupant.

  However, in the conventional structure disclosed in Patent Document 1, since the door is moved outward by a plurality of extrusion mechanisms having pistons and inflators, not only a large driving force is indispensable, but also the device There was a problem that became complicated.

On the other hand, in Patent Document 2, in a vehicle in which the hinge of the front door can be forcibly moved to the outside of the vehicle, when the acceleration sensor detects a collision, the inflator is actuated to unlock the hinge of the front door. By forcing the front door out, the impact on the front pillar is effectively absorbed and mitigated without hindering the deformation of the front pillar at the time of collision.
However, Patent Document 2 does not disclose a technical idea of expanding the space between the seat and the door by moving the door outward.
