Abstract
A telescopic safety steering column for motor vehicles which includes a steering wheel displaceable from its normal operating position relative to the outer steering column under energy absorption by the steering wheel and an energy-absorbing support of the outer column at a fixed vehicle part; this support being provided by an undulated tubular member which is arranged parallel to the center longitudinal axis of the safety steering column and is stable as regards its position while the fixing of the outer column is provided in proximity to the steering wheel by a guide strap which becomes ineffectual when the body of a vehicle passenger impinges against the steering wheel.
Claims17
In a telescopic safety steering column for motor vehicles which includes an outer column means, a steering wheel displaceable relative to said outer column means under energy absorption, and energy-absorbing support means for supporting said outer column means at a fixed vehicle part, the improvement comprising said energy-absorbing support means including an undulated tubular member stably arranged parallel to the center longitudinal axis of said safety steering column, and fixing means for fixing said outer column means to said fixed vehicle part in proximity to said steering wheel, said fixing means including guide means for guiding said tubular member with respect to said axis upon impact against said steering wheel, characterized in that the guide means includes a guide strap, and characterized in that a bracket means which accommodates one end of the tubular member projects from the outer column means, the tubular member being pressed against the fixed vehicle part by said bracket means, and in that a cover means partly surrounding the tubular member and stressable in tension is provided which is connected with the fixed vehicle part.
