PCT No. PCT/EP94/01052 Sec. 371 Date Oct. 2, 1995 Sec. 102(e) Date Oct. 2, 1995 PCT Filed Apr. 5, 1994 PCT Pub. No. WO94/23859 PCT Pub. Date Oct. 27, 1994Traction 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. The rotation of the base of the traction arm about these axes can be individually locked by virtue of associated locking elements that can be activated or deactivated in order to vary the position of the post with respect to the repair bench according to the requirements arising from the position of the portion of the object to be repaired and from the direction of the force to be applied to this portion to repair it. |
