Problems solved by technology

[0005] It has been found to be disadvantageous in the actuating device that an undesirably high friction force occurs when pressing the button to actuate the actuating device, that is to say, the operator has to expend effort in order to be able to press the button. relatively high force
[0006] This is perceived as uncomfortable by the operator, ie the actuating device has reduced operator-friendliness

Embodiment Construction

[0029] figure 1 A handbrake lever of an actuating device 1 for a parking brake in a vehicle is shown.

[0030] The handbrake lever 1 has a receptacle 2 in which a bearing seat (not shown) can be fastened as part of the actuating device, so that the handbrake lever is pivotable about a horizontal axis supported on the bearing housing. The handbrake lever 1 has a base body whose front end is formed in the form of a pipe section 3 . A handle (not shown) can be supported on the pipe section 3 .

[0031] The corresponding position of the handbrake lever 1 is transmitted via a cable drive (not shown) to a parking brake (not shown) of the vehicle.

[0032] An actuation lever (not shown) can be supported on the handbrake lever 1 . The actuating lever is guided in the pipe section 3 of the handbrake lever 1 . The operating rod protrudes from the front end of the pipe section 3 . A button (not shown) is fixed on the front end of the fixing rod. The button is actuated against the ...

Abstract

The invention relates to an activation device for a parking brake comprising a handbrake lever (1) which is pivotably mounted on a bearing block, and a securing device (4) for securing the handbrake lever (1) in a latched position. The securing device (4) has a detent pawl (5) which is arranged on the handbrake lever (1) in such a way that it can pivot about a pivoting axis, and a locking segment (6) which is permanently connected to the bearing block. The detent pawl (5) is engaged in a latching position on the locking segment (6) and is held there by the spring force of a leg spring (8). The detent pawl (5) and the leg spring (8) are secured to the handbrake lever (1) by means of a connecting element (7). The leg spring (8) is secured against displacement in three spatial directions by position-securing means.

Description

technical field [0001] The invention relates to an actuating device for a parking brake according to the preamble of claim 1 . Background technique [0002] An actuating device for a parking brake is known from DE 20 2009 008 792 . The operating device includes a hand brake lever that is pivotably supported on a bearing seat. For actuating the parking brake, a single actuating lever is provided as an actuating transmission lever, which cooperates with the fastening device. The operating rod extends in a tubular receptacle of the handbrake lever. On the front end of the actuating lever is arranged a button which protrudes beyond the tubular receptacle and which can be actuated by the operator. [0003] The parking brake consists of a locking segment and a locking pawl. The stop segment is fixed on the bearing seat and has a half bar with locking teeth. The locking pawl is pivotably mounted on the connecting element of the lever of the finger by means of a Belleville spri...
