A method and apparatus for the production of a synthetic resin skin uses a mold for forming at least two separate skin sections which are then joined prior or after a final heat treatment. The synthetic resin skin sections are produced in at least two separate mold members, and the skin sections are then caused to contact each other along determined faces or margins which are joined under light pressure. Any so-called selvage is easily removed after the joining which intimately bonds the skin sections to each other due to the curing of the synthetic resin.

A motor vehicle door lock is equipped for cooperation with a central locking system able to lock all doors of a vehicle from a single control. The lock also has a pull closed mechanism which is driven by the same motor driving the locking elements in response to a signal from the central locking system. The pull closed mechanism cooperates with a fork latch for bringing the fork latch from a preliminary latching position into a main or final latching position, whereby door slamming for properly closing a vehicle door is not necessary. It is now sufficient if the user closes the door so that the fork latch is in its preliminary latching position since the present invention mechanism will then close the vehicle door completely.

Apparatus for producing a synthetic resin skin

A thin-walled work piece of plastics material is cast in a mold by pouring or flowing the plastics material in the form of a plastisol or a flowable powder into a preheated casting mold which is locked to a casting container in a sealed manner to form a closed casting cavity. The mold and the container are then lifted or rotated through at least 180.degree.. A reduced pressure is maintained in the cavity at least prior and during the tilting. After a predetermined time the reduced pressure is removed and the mold and container are tilted back into the starting position. The mold and container are then separated again and the mold is then heated for completion of the jelling or curing whereupon the mold is cooled for removing the work piece from the mold.
