Abstract: Seal preferably intended to be used for door locks on motor vehicles. The seal comprises an annular base part, an annular combined sealing surface made up of a first part surface and a second part surface which intersect at an intersection region at an angle .beta., and an annular flexible element connecting the base part with the combined sealing surface. The seal is arranged such that, for example, when a vehicle door to which the lock is fitted is in a non-sealing position, the first part surface of the combined sealing surface forms an angle .alpha. in relation to a plane A--A which is parallel to the part of the door which is to be sealed.
