Title
(EN) ENERGY ABSORBING SEAT BELT RETRACTOR
(FR) DISPOSITIF DE RAPPEL DE CEINTURES DE SECURITE, ABSORBANT L'ENERGIE
Abstract
(EN) A seat belt retractor (50) has a spool (56) about which a seat belt is wound. A locking mechanism (60) at least initially locks the spool against rotation. A primary force-limiting mechanism, such as a torsion bar (58), permits the spool to rotate in a controlled manner subsequent to the locking of the spool. A secondary force-limiting mechanism is located within a recess (100) in the spool and comprises portions of the spool and an adjacent portion of the locking mechanism to increase the restraining force on the seat belt before the primary force-limiting mechanism becomes effective. The torsion bar (58) is connected at one end to the spool and at its other end to the locking mechanism. The secondary locking mechanism includes a recess, keyway or slot (102) and a projection (104) formed on one of the bore and an interlocking part of the locking mechanism.
(FR) Ce dispositif de rappel (50) de ceintures de sécurité comprend une bobine (56) autour de laquelle la ceinture est enroulée. Un mécanisme de blocage (60) bloque au moins initialement la bobine, afin de l'empêcher de tourner. Un premier mécanisme de limitation de force, tel qu'une barre de torsion (58), permet à la bobine de tourner de manière commandée, après qu'elle ait été bloquée. Un second mécanisme de limitation de force, monté dans un évidement (100) ménagé dans la bobine, comprend des portions de la bobine ainsi qu'une portion adjacente du mécanisme de blocage, afin d'accroître la force de retenue exercée sur la ceinture de sécurité avant que le premier mécanisme de limitation de force ne devienne opérationnel. La barre de torsion (58) est reliée à la bobine, au niveau d'une de ses extrémités, et au niveau de son autre extrémité, elle est reliée au mécanisme de blocage. Le second mécanisme de blocage comprend un évidement, une rainure de clavette ou fente (102), un élément saillant (104) formé sur l'un des alésages, et une partie d'enclenchement du mécanisme de blocage.
