The actuation unit for a stroller braking device comprises a handle (39) that is arranged in a housing (50), is pivotally mounted, and has a receptacle to which a coupling element can be fastened to operatively connect the handle (39) to the stroller braking device. The handle (39) can pivot from a central position in a first direction (74) to a first pivoted position in order to create a braking function of the braking device and can pivot, once again from the central position, in a second direction (76), counter to the first direction, to a second pivoted position to create a parking brake function of the braking device. The actuation unit comprises a releasable locking mechanism (80) that includes an axially movable release button (78) for automatically locking the handle (39) in the second pivoted position. The locking mechanism (80) also includes a locking projection (94), coupled to the release button (78), for engagement in a corresponding locking recess (98) of the handle (39). In the second pivoted position of the handle (39), in which the locking projection (94) engages in the locking recess (98), the release button (78) is in a deployed position in which the release button (78) partially projects from the housing (50). The release button can be manually moved back into the housing (50), against the biasing force, into a retracted position in order to unlock the locking mechanism (80) and remains in the retracted position in other pivoted positions of the handle (39). |
