Abstract
A lock which operates reliably and quietly has a locking mechanism with a rotary latch and at least one ratchet pawl for latching the rotary latch. The lock comprises two faces which at least partially bear one against the other and which are at least recurrently displaced relative to one another, with the result that that the displacement causes frictional forces to occur between the faces. At least one frictional face is part of a rotatable component of the lock. A lubricant reservoir is assigned to this rotatable component. There is a feeding means from the lubricant reservoir to the frictional face, which means is configured in such a way that the lubricant is transported from the lubricant reservoir to the frictional face of the rotatable component.
