VEHICLE DRIVER STATE DETECTION APPARATUS
First Claim
1. A vehicle driver state detection apparatus, comprising:
- a panel surface that includes one of an instrument panel and a meter cluster;
a steering column portion that supports a steering shaft of a vehicle;
a displacement absorbing portion that absorbs displacement caused by an impact applied to the steering column portion in an axial direction of the steering column portion; and
a driver state detection portion that is attached to an outer peripheral surface of the steering column portion,wherein the driver state detection portion is provided on the outer peripheral surface of the steering column portion at a portion that is distant from the panel surface toward a side of a steering wheel so that a distance between the portion and the panel surface is larger than a maximum amount of the displacement absorbed by the displacement absorbing portion.

Abstract
A vehicle driver state detection apparatus includes: a panel surface that includes an instrument panel or a meter cluster; a steering column portion that supports a steering shaft of a vehicle; a displacement absorbing portion that absorbs displacement caused by an impact applied to the steering column portion in an axial direction of the steering column portion; and a driver state detection portion attached to an outer peripheral surface of the steering column portion . In the vehicle driver state detection apparatus, the driver state detection portion is provided at a portion at which the driver state detection portion does not contact the panel surface when the displacement is absorbed.

3. A vehicle driver state detection apparatus, comprising:
-
a meter cluster having a lower side member; a steering column portion that supports a steering shaft of a vehicle; a displacement absorbing portion that absorbs displacement caused by an impact applied to the steering column portion in an axial direction of the steering column portion; and a driver state detection portion attached to an outer peripheral surface of the steering column portion; wherein a portion on the outer peripheral surface of the steering column portion at which the driver state detection portion is provided and a surface of the lower side member of the meter cluster directed to the driver state detection portion form an obtuse angle, and wherein the driver state detection portion is provided so that the driver state detection portion is detached from the outer peripheral surface of the steering column portion when a predetermined or larger external force is applied to the driver state detection portion. - View Dependent Claims (5, 11, 12, 13, 14, 15)
