Abstract: A device for absorbing shocks of a liftable and lowerable object such as a spare tire includes a reeling device that contains a hoisting cable, the reeling device rotatably attached to the vehicle chassis, an arresting device that under normal conditions prevents the reeling device from rotating relative to the vehicle chassis but enables the reeling device to rotate relative to the vehicle chassis under crash conditions thereby absorbing significant part of the energy of the shock.

Abstract: A device for absorbing shocks of a liftable and lowerable object such as a spare tire includes a first hoisting cable having a hoist-side end and an object-side end and a hollow cylinder encompassing a folded or coiled length of the first hoisting cable near the object end inside the cylinder. Lower and upper ferrules at the lower and upper ends of the cylinder are held in position by a second auxiliary cable having two ends, each end attached to one of the ferrules, the second auxiliary cable having a smaller tearing strength than the first hoisting cable.

Abstract: The invention provides a joint for the transmission of rotational motion between two rotatable elements, including a first, driven, element consisting of a shaft portion and a head portion, the head portion including a first recess and a second, contiguous, recess in the form of the female partner of a coupling having coupling faces, and a second, driving, element consisting of a shaft portion, a collar portion of a diameter freely fitting into the first recess, and the male partner of the coupling, wherein the respective dimensions of the coupling faces of the male and female partners differ to such an extent that the second element is tiltable out of alignment with the first element while retaining its engagement with the first element.
