Abstract
Braking device for safety belts which have a braking system ahead of the braking device, which latter has movable brake roller partly wrapped around by the belt, a stationary clamping bar disposed adjacent one side of the belt, and a movable arresting element. Upon activation resulting from a belt pull which exceeds a predetermined force, the brake roller is moved out of position against the arresting element which latter moves toward the stationary pad to cause clamping of the belt and which also arrest the brake roller by contact therewith.
Claims12
Braking device for safety belts, especially safety belts for motor vehicles, which have a locking system ahead of the braking device, comprising a bracket, a movable brake roller partly wrapped around by the belt rotatably supported in the bracket, means sufficient to retain said brake roller in position during normal operation but insufficient to prevent movement of said brake roller out of position when activated by a belt pull which exceeds a predetermined force, a stationary clamping bar disposed adjacent one side of the belt near said brake roller, a movable arresting element having one portion near said movable brake roller and another portion disposed on the side of the belt opposite the side on which said stationary clamping bar is disposed , said arresting element including means for arresting rotation of said brake roller when said arresting element and brake roller are in contact, whereby, upon activation of a belt pull in excess of said predetermined force movement of said brake roller out of its normal position and against said arresting element which latter moves toward the stationary clamping bar to cause clamping of the belt and which also arrests the brake roller by contact therewith, and wherein braking friction between the roll surface of said brake roller and said belt partly wrapped around said brake roller is great enough so that a force moment is transferred to said arresting element which is sufficient to clamp the belt by means of the arresting element without slippage.
Braking device for safety belts, especially safety belts for motor vehicles, which have a locking system ahead of the braking device, comprising a bracket, a movable brake roller partly wrapped around by the belt rotatably supported in the bracket, means sufficient to retain said brake roller in position during normal operation but insufficient to prevent movement of said brake roller out of position when activated by a belt pull which exceeds a predetermined force, a stationary clamping bar disposed adjacent one side of the belt near said brake roller, a movable arresting element having one portion near said movable brake roller and another portion disposed on the side of the belt opposite the side on which said stationary clamping bar is disposed and wherein said arresting element is formed as a two-armed rocker arm, and is hingeably supported against a spring force, and wherein at one rocker arm disposed near said brake roller are arresting means for arresting the rotation of the brake roller when in contact therewith, and at the other arm of the rocker opposite the side of the belt on which clamping bar is disposed is a pressure pad which presses the belt onto the clamping bar whereby, upon activation of a belt pull in excess of said predetermined force, movement of said brake roller out of its normal position and against said arresting element which latter moves toward the stationary clamping bar to cause clamping of the belt and which also arrests the rotation of the brake roller by contact therewith.
