A fluid-damped automotive door latch actuator (14) comprising a fluid cylinder (30) mounted adjacent the inside surface of an escutcheon plate (10) between the door handle crank arms (20, 22). A shaft (24) connected to and extending between the crank arms (20, 22) is rotated to actuate the door latch. Damping action is caused in one embodiment by rotation of a shaft-mounted vane (32) relative to a cylinder housing (34) fixed to the escutcheon plate (10). In a second embodiment, the damper (30) is designed to provide a fluid shearing action.

L'invention concerne un actionneur de verrouillage de portière automobile amorti par fluide (14) comportant un vérin hydraulique (30) monté adjacent à la surface intérieure d'une plaque d'écusson (10) entre les bras de manivelle (20, 22) de la poignée de portière. Un arbre (24) relié aux bras de manivelle (20, 22) et s'étendant entre ces derniers est mis en rotation pour actionner le verrouillage de portière. Dans un mode de réalisation, un effet d'amortissement est provoqué par la rotation d'une aube (32), montée sur l'arbre, par rapport à un carter de vérin (34) fixé à la plaque d'écusson (10). Dans un deuxième mode de réalisation, l'amortisseur (30) est conçu pour assurer une action de cisaillement du fluide.
