摘要： Apparatus for supporting a steering column of an automotive vehicle includes a mounting bracket secured to the steering column. Upper fasteners rigidly secured to vehicle support structure extend through longitudinally extending upper slots in the mounting bracket. Lower fasteners rigidly secured to the vehicle support structure extend through longitudinally extending lower slots in the mounting bracket. The connection of the fasteners in the slots of the mounting bracket releases in response to longitudinal collapse of the steering column in a frontal impact. The vehicle support structure overlies the mounting bracket to resist upward displacement of the mounting bracket when the steering column collapses. Pull loop assemblies are associated with the lower fasteners. Each pull loop assembly includes a generally U-shaped strap of flexible, bendable material having a first leg connected to one of the lower fasteners. Each strap has a second leg which is unattached. Each strap has a return bent intermediate portion extending over a fixed support frame on the mounting bracket so that when the bracket collapses with the steering column, the straps will unwind around and be pulled over the fixed support frame and thereby resist such collapse and absorb energy.

摘要： The present invention provides a way in which the coefficient of friction between the steering column and the instrument panel may be lessened when an isolator pad is used. The reduction in friction is accomplished by impregnating the isolator pad with a lubricant.

摘要： A vehicle steering mechanism can be supported for controlled collapse in crash situations, by constructing the support mechanism as a rigid assembly having a metal die casting as a principal component. The rigid die casting transmits a shock force from the vehicle steering wheel to shearable fasteners that connect the die casting to a mounting structure on the vehicle. Undesired resilience or spring in the steering shaft support mechanism is eliminated, such that the system has a desired predictability in frontal crash situations.
摘要翻译： 通过将支撑机构构造为具有金属压铸件作为主要部件的刚性组件，可以支持车辆转向机构用于在碰撞情况下的可控塌陷。 刚性压铸将来自车辆方向盘的冲击力传递到将压铸件连接到车辆上的安装结构的可剪切紧固件。 消除了转向轴支撑机构中不期望的弹性或弹簧，使得系统在正面碰撞情况下具有期望的可预测性。

摘要： A telescoping steering column is provided with a simple means to allow ease of movement of a telescoping steering shaft through a plurality of positions. This is accomplished by placing a biasing component on an exterior of a movable portion of the steering column to bias the movement of that portion.
