Abstract: A detent mount bracket for an adjusting device in a motor vehicle seat includes first and second hinge parts that are adjustable with respect to each other about a hinge axis. A stopper part is slidably disposed between a detent position and a release position on the first hinge part, and comprises an outer toothed surface and a first control region. An adjusting part is connected to a shaft and comprises a second control region cooperating with the first control region. An elastic means biases the stopper part in the detent position. On the second hinge part defines an inner toothed surface, which mates with the outer toothed surface. The stopper part is axially slidably disposed on the first hinge part, is substantially non-rotatably disposed, and is spaced an additional axial distance apart from the first hinge part in the detent position than in the release position.
