Vehicle seat latch

1. A latch for a vehicle seat, comprising:

a detent which is pivotable about a detent axis between a release position and a locking position, for co-operating with a closure bolt or a curved closure member; and

an ejector having a resilient element which is arranged in a housing of the latch,

wherein the ejector with the resilient element which is pretensioned is capable of being brought into abutment with the closure bolt or curved closure member,

wherein the ejector has a sliding ejection member which is acted on by the resilient element,

wherein the sliding ejection member comprises two arms, one arm being constructed so as to be longer than the other arm, and a contact face being provided at an end of the longer arm facing away from the resilient element.

2. The latch as claimed in claim 1 , wherein the housing of the latch has a receiving member with a slot, one end of the receiving member is open in an outward direction and the other end of the receiving member is closed with a base.

3. The latch as claimed in claim 2 , wherein the closure bolt is introducible, transversely relative to the longitudinal extent thereof, into the receiving member and is engagable by the detent at a side of the closure bolt facing away from the base.

4. The latch as claimed in claim 1 , wherein the detent is acted on by a resilient force of a detent spring, which produces a torque which acts on the detent in the unlocking direction.

5. The latch as claimed in claim 1 , wherein the resilient element is constructed as a pressure spring and is supported on the housing of the latch, the resilient element being clamped between the housing and the sliding ejection member.

6. The latch as claimed in claim 1 , wherein the resilient element is constructed as a cylindrical helical spring.

7. The latch as claimed in claim 1 , wherein the sliding ejection member has a cylindrical recess, in which the resilient element is fitted.

8. The latch as claimed in claim 1 , wherein the sliding ejection member engages round a stop at two sides.

9. The latch as claimed in claim 8 , wherein the stop is constructed integrally with the housing and forms the base.

10. The latch as claimed in claim 1 , wherein the longer arm of the sliding ejection member protrudes with the contact face beyond the base into a region of a receiving member.

11. A vehicle seat, in particular a motor vehicle seat, having a latch as claimed in claim 1 .

12. The vehicle seat as claimed in claim 11 , comprising:

a backrest which is pivotable relative to a vehicle structure from a position for use into a non-use position and which is lockable in the position for use,

wherein the latch is connected to the backrest, and

wherein the detent, when the backrest is in the position for use, is in locking engagement with the closure bolt or the curved closure member of the vehicle structure,

wherein the unlocked backrest is pivotable by a specific extent from the position for use into an ejection position by the ejector,

wherein, when the backrest is in the position for use with a pretensioned resilient element, the ejector is in abutment with the vehicle structure or the closure bolt or curved closure member.

13. The vehicle seat as claimed in claim 11 , wherein a pivot movement of the backrest from the ejection position into the position for use is counteracted by a force which is applied by the resilient element and which corresponds to or is greater than a force acting on the backrest in the direction toward the position for use owing to an inherent weight of the backrest.
