Title:
ENERGY-ABSORBING STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/026258
Kind Code:
A1
Abstract:
[Problem] To create a structure whereby, upon a second impact, a steering wheel faces forward and displaces smoothly, even when the structure is provided such that an electric motor (13a) that is part of an electric power steering device protrudes sideways. [Solution] The distances from the centerline of a steering column (6c) to joints between mounting plates (17e or 17f) and parts (34) affixed to the vehicle body are different on either side of the steering column (6c). Said distance (Le) to the mounting plate (17e) on the side where the electric motor (13a) is installed is shorter than said distance (Lf) to the mounting plate (17f) on the side opposite the electric motor (13a). The proportion of a separation load applied to the mounting plate (17e) on the side where the electric motor (13a) is installed is made higher. The tendency to resist falling forwards on the side where the electric motor (13a) is installed, which has a high inertial mass, is counterbalanced by the increased propensity of that mounting plate (17e) to fall.
