A safety steering-wheel has a rim situated in front of a central hub of the wheel. Only two legs are fixed to the rim and are inclined therefrom rearwardly toward the central hub, these legs when projected onto a plane which contains the rim extending along radii of the latter which are situated relatively close to each other. At least one of these legs is fixed to the hub. Fixed to the hub or at least one of the above legs is a substantially gallows-shaped complementary portion which is situated in the vicinity of the hub, with this complementary portion situated behind the plane of the rim but forwardly of the hub. The above legs and complementary portion when projected onto a plane which contains the central axis of the hub form a substantially V-shaped configuration, the crest of which is situated adjacent the hub, the complementary portion being inclined oppositely to the legs and extending to the side of the hub axis opposite from the legs. In case of an accident, the crushing force exerted by the driver thrown against the steering-wheel will cause flattening and collapsing of the legs while the complementary portion will absorb the shock of the driver's body before the latter can reach the hub.
Safety steering-wheel including a central hub having a hub axis and a rim situated in a predetermined rim plane located in front of said central hub, the said steering-wheel including only two deformable legs fixed to said rim and inclined rearwardly therefrom toward said hub, with at least one of said legs being fixed to said hub, said legs when projected onto said rim plane being directed substantially along two radii in proximity to one another leaving a greater part of the rim which extends through more than 180.degree. around said axis deprived of any point of attachment with a leg, at least one of said legs and said hub respectively having portions at least one of which is a fixing portion, the said steering-wheel comprising a complementary portion inclined to the axis of the hub, substantially in the shape of a gallows, having a pair of feet at least one of which is fixed near the hub to said fixing portion, and said complementary portion extending well in front of the hub, but behind the rim plane to a side of the hub axis opposite from said steering-wheel legs, said feet respectively forming substantially prolongations of the said legs when projected onto said rim plane.
