摘要： The invention relates to safety belts of the wind-up type for vehicles. In these safety belts the belt strap, connected to a shaft rotatably mounted in a casing and tending to be reeled up on the shaft by the action of a spiral spring member tightened by the unwinding of the strap from the shaft when the strap is pulled out and laid across the chest of the strapped user, exerts an often unpleasant pressure on the chest of said user. The invention provides a means adapted to counterbalance this pressure when the strap approaches and is kept in the position of use across the chest of the user, but not to interfere with the retractive or reeling-up force exerted by the spiral spring member on the strap in positions outside said position of use.
