An aid to improve a golf participant's golf swing for developing an accurate and powerful golf swing technique. The inventive device includes an arm strap assembly, a trigger assembly, a ratchet assembly and a club clip attachment. The arm strap assembly attaches to the player's trailing arm by adjustable straps. The trigger assembly includes a trigger line of fixed length and connects the arm strap to the ratchet assembly. One purpose of this component is to “trigger” the point at which the ratchet mechanism should release the ratchet line. The ratchet assembly consists of a retracting, spring-loaded release device that remains locked as long as the trigger mechanism is slack. Once the trigger mechanism exceeds a preset pull-force, the ratchet mechanism releases allowing the ratchet line connected between the ratchet assembly and the participant's golf club to extend at the appropriate position in the participant's down swing. In turn, this allows the participant to extend his trailing arm resulting in the generation of maximum force to be imparted to the golf ball at the point of impact.

A pivot bearing used in a vehicle trailing arm suspension includes a housing, a resilient bush compressed and bonded in the housing, and a rigid axial sleeve in the bush. The bush has voids, above and below the sleeve when the pivot bearing is fitted for use and stiffening elements which extend between the voids at opposite sides of the sleeve. When the pivot bearing is in use in a vehicle trailing arm suspension, the voids increase flexibility of the bush under generally vertical loading on the pivot bearing. The stiffening elements enhance the stiffness of the bush in generally horizontal direction for improved vehicle dynamics and reduced vibration. Preferably, the stiffening elements are of plate or leaf form, are bonded to the bush, and extend arcuately about the sleeve. The voids extend partially through the axial thickness of the bush from opposite ends of the bush and generally accurately about the sleeve. The bush also has enlarged opposite circumferential end portions. The end portions extend circumferentially beyond diametrically opposite parts of the external circumference of the sleeve and are in-turned towards the sleeve. Edges of the stiffening elements extend into the opposite end portions of the voids.
