Abstract
A seat for fastening the curved tube of a bicycle V-type brake is composed of two connection members, a seat body, and a torsion spring. The connection members are fastened pivotally and coaxially with a first brake arm of the bicycle V-type brake by a first pivot. The seat body is fastened pivotally with the connection members by a second pivot and is provided with a first retaining portion. The seat body has an end plate, which is fastened with one end of the curved tube. The torsion spring is fitted over the second pivot such that one end of the torsion spring urges the first pivot, and that another end of the torsion spring urges the first retaining portion of the seat body. When the brake cable is triggered, the first brake arm and the second brake arm are actuated to cause the brake shoes to make contact with the wheel rim. In the meantime, the seat body is caused to swivel by a reaction force which is brought about by the brake cable and is greater than the torsional force of the torsion spring. The torsion spring serves to provide a damping effect to prolong the lock-up time of the brake shoes. The value of the torsional force of the torsion spring can be changed by rotatin…
