Abstract
Abstract A safety steering wheel for motor vehicles in which the steering wheel rim, the steering wheel spokes and the hub as well as the deformation member are surrounded with a relatively soft elastic synthetic resinous material and in which a large impact surface is provided on the inside of the steering wheel rim which preferably does not extend significantly below the plane of the steering wheel rim; the steering wheel spokes are elastic and may be made, for example, of band steel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
A safety steering wheel for motor vehicles, comprising a steering wheel rim, a hub being operatively connected with a steering spindle, elastic steering wheel spoke means consisting of band steel operatively associated with the steering wheel rim and the steering spindle, deformation means being operatively arranged between the end of the steering spindle and the top side of the steering wheel facing the driver, said steering wheel rim, said steering wheel spoke means, said hub and said deformation means being surrounded with relatively soft, elastic, foamed synthetic resinous material, an impact surface provided within the steering wheel rim, which surface does not extend substantially below the plane of the steering wheel rim, and at least one deformable insert means being provided on the inside of the deformation means, wherein said insert means is substantially star-shape as viewed in plan view.
