Patent ID: 7275771

Claim:
A lock ( 1 , 1 ′) for a door of a motor vehicle comprising: a closing mechanism ( 3 ) designed for coupling, in a releasable way, with a lock striker ( 2 ) for bringing about closing of the door; a mechanical actuating assembly ( 4 ) of said closing mechanism ( 3 ), including opening means ( 30 , 38 , 55 , 57 ), for controlling release of said closing mechanism ( 3 ) from said lock striker ( 2 ), and means for inhibiting opening ( 41 , 58 ), in turn including a first safety member ( 41 ) and a second safety member ( 58 ), that can be selectively activated for rendering said opening means ( 30 , 38 , 55 , 57 ) ineffective, respectively, from outside and from inside the motor vehicle; and electrical actuator means ( 5 ) including a first output member ( 71 ) coupled with said first safety member ( 41 ), said electric-actuator means ( 5 ) being housed in a fluid-tight way in a single casing ( 70 ) and said first output member ( 71 ) traversing, in a fluid-tight way, a through hole ( 73 ) of said casing ( 70 ) for co-operating with said first safety member ( 41 ), and said electric-actuator means ( 5 ) including a second output member ( 72 ) coupled with said second safety member ( 58 ), housed in a fluid-tight way in said casing ( 70 ) and traversing in a fluid-tight way a further through hole ( 74 ) of said casing ( 70 ), and wherein said casing ( 70 ) defines an area ( 70 a ) for housing a manual control device ( 82 , 156 ) of said first output member ( 71 ) and an additional electrical control device ( 155 ) of said second output member ( 72 ), which provides a function of child safety of said lock ( 1 , 1 ′).
