Description

technical field [0001] The invention relates to a recliner for a motor vehicle having a wedge capable of controlling the inclination of the vehicle seat backrest. In particular, the invention relates to a recliner for a motor vehicle having a wedge which improves the play and strength of the recliner. Background technique [0002] Generally, a vehicle seat is configured with a seat cushion and a seat back to maintain the posture of a passenger in the vehicle, and the vehicle seat is classified into a split type seat and a bench type seat, and the split type seat is formed on the driver's seat. The seat and the passenger seat are designed to allow only one person to sit, while bench type seats are formed at the back of the driver's seat and the passenger seat to enable a plurality of people to sit at the same time. [0003] The separate type of seat formed at the driver's seat and the passenger's seat can control the vehicle seat to conform to the type of the driver's body a...

In this case, since the lock gear 2 moves along the guide surface 3a, a gap G is required between the lock gear 2 and the guide surface 3a (see figure 2 ), when the gap G is increased according to the accumulation of machining tolerances of the lock gear 2 and the bracket 3, in the state where the lock gear 2 meshes with the upper gear 1, the bracket 3 moves largely, thus creating a backlash and vibrating the seat back , and thus passenger comfort is reduced

[0007] However, the gap G cannot be eliminated due to the accumulation of machining tolerances of the components of the locking gear 2 and bracket 3
