## Abstract

A disc brake for a vehicle, in particular for a commercial vehicle, is provided. The disc brake includes at least one application-side brake pad and a back-side brake pad held in a form-fitting manner in a brake carrier. At least the application-side brake pad is provided with at least one pad-retaining spring which is supported at least on one brake carrier horn of the brake carrier and exerts a radially outwardly acting tensile force on the brake pad.

## Claims

### Claim 1

A disc brake for a vehicle, comprising:
a brake disc having a brake disc rotational axis;
a brake carrier configured to straddle the brake disc;
an application-side brake pad and a back-side brake pad with respective back plates configured to be supported directly on the brake carrier in respective brake carrier pad slots;
a brake caliper configured to straddle the brake disc while being supported on the brake carrier in a manner that enables sliding of the brake caliper relative to the brake carrier along a direction parallel to the brake disc rotational axis;
at least one pad-retaining spring coupled to the application side brake pad,
wherein
the brake carrier and at least the application side brake pad have form-fitting complementary contours configured such that the form-fitting complementary contours directly abut one another when at least the application side brake pad is in an installed position in the brake carrier to constrain the application-side brake pad against radial movement away from the brake disc rotational axis,
the at least one pad-retaining spring is configured to be supported at opposite ends directly on brake carrier horns adjacent to the application-side brake carrier pad slot and to exert a tensile force in a radially outward direction on the application-side brake pad,
the form-fitting complementary contours include opposing brake carrier projections into the application-side brake carrier pad slot and complementary recesses in opposite lateral sides of the application-side brake pad,
undercut surfaces of the contours of the brake carrier horns are configured to engage in a play-free manner undercut surfaces of projections of the pad back plate located radially inward of the brake pad recesses,
the at least one pad-retaining spring is located on an upper side of the application-side brake pad back plate,
the at least one pad-retaining spring includes a central section, arm sections adjacent to opposite ends of the central section, pressure sections adjacent to the arm sections, and intermediate sections between the central section and the adjacent arm sections, and
the central section is attached to the application-side pad back plate by at least one fastening element and the pressure sections extend laterally beyond the lateral sides of the application-side brake pad back plate a distance sufficient to be supported on the brake carrier horns.

### Claim 2 (depends on 1)

The disc brake according to claim 1, wherein
the at least one fastening element includes a transverse section extending through an opening in the application-side brake pad back plate and an upper section extending over the pad-retaining spring such that the pad-retaining spring passes between at least one fastening element and the upper side of the application-side brake pad back plate.
