Abstract: Traction and alignment arm, particularly for motor vehicle body repair benches, including a base which is associable with a repair bench and a post that extends from the base and has traction elements for engaging a portion of the object to be repaired which is placed on the bench. The traction arm includes: a first supporting plate slidably connected to a beam of the bench; a second supporting plate pivotally connected to the first plate for the rotation of the base about a first axis that is substantially horizontal and substantially at right angles to the front plane of the first plate for applying the base to the repair bench; a third supporting plate pivotally connected to the second plate for the rotation of the base about a second axis that is substantially at right angles to the first axis; and pivoting elements for the rotation of the base about a third axis (its own axis) that is substantially at right angles to the second axis.

Abstract: A motor vehicle body repair bench comprising a standard support for body repairing jigs, made of a bracket having a horizontal cross-shaped slide supporting a vertically slidable rod provided with an upper member of inverted U-shape. The standard support is mounted on a crossbeam and has three degrees of freedom of movement within its structure so that the upper member of inverted U-shape will reproduce adjacent the motor vehicle body a portion of the crossbeam. The universality of the standard support permits the use of body repairing jigs of reduced dimensions, which are mounted on the member of inverted U-shape, and permits positive repairing operations to be carried out in any position on the motor vehicle body.
