Occupant restraint device control device

Abstract

To ensure grounding performance similar to prior forms despite a resin case, the disclosed occupant restraint device control device having an electric circuit board (2) incorporates a control circuit which determines whether or not a vehicle (6) has collided using the detection output from a sensor which detects the acceleration / deceleration of the vehicle (6) and which outputs a control signal which activates an occupant restrainer. A resin case (1) houses the electric circuit board (2) within, and is provided with a ground electrode lead-out structure which leads from the inside to the outside. The ground electrode lead-out structure is provided with attachment legs (1b) to which the electric circuit board (2) is attached within the case (1), and is configured with a ground lead-out member (3), which connects the attachment legs (1b) to the vehicle (6) attachment portion (1a). The ground lead-out member is provided with a first spring structure section (3a) which is sandwiched between an attachment leg (1b) and the electric circuit board (2); a ground terminal section (3b) which is sandwiched between the case (1) and a portion of the vehicle (6); and a second spring structure section (3c) which connects the first spring structure section (3a) and the ground terminal section (3b). Thus, even when a resin case is used, satisfactory earthing performance and sensing performance similar to prior forms are possible.

Description

technical field [0001] The present invention relates to a driver and passenger restraint device control device for electrically controlling the activation of a driver and passenger restraint device installed on an automobile as a safety device. Background technique [0002] For example, an airbag device that deploys an airbag by gas to restrain the occupant during a collision and protects the occupant from the impact of the collision has an airbag control device that electrically controls the deployment of the airbag. [0003] The structure of the safety airbag control device is provided with a sensor for detecting acceleration or deceleration, and an electronic circuit substrate, wherein a control circuit is assembled on the electronic circuit substrate, and the control circuit judges whether the vehicle has collided based on the detection output of the sensor, and the output is used for deployment. Airbag control signal. [0004] The case for accommodating the electronic ...
