Claim:
1. A locking device for a vehicle seat, comprising: a pawl which is mounted such that it can be pivoted about a second axis in order to lock a counterelement; a clamping eccentric which is mounted such that it can be pivoted about a first axis which is parallel to the second axis and secures a locked state of the pawl by interaction with a first functional face of the pawl, the clamping eccentric acting in a spring-loaded manner on the first functional face via a clamping face in the locked state, the clamping eccentric exerting a closing moment on the pawl in the locked state, wherein the clamping eccentric can be moved out of its locked location into its unlocked location; and a prestressed compression spring being provided which is supported with its one end on an arm of the clamping eccentric so as to spring-load the latter into its locked location and loads the pawl in the unlocking direction with its other end, wherein a first lever arm between the action point of the compression spring on the pawl and the second axis is greater than a second lever arm between the action point of the compression spring on the clamping eccentric and the first axis, wherein a third lever arm between the contact point of the first functional face on the clamping face and the second axis is greater than a fourth lever arm between the contact point of the first functional face on the clamping face and the first axis, wherein the ratio of third lever arm to fourth lever arm is greater than the ratio of first lever arm to second lever arm.
