  • Patent number: 10173487
    Abstract: A joint device (6) including an axially extending pivot pin (8) and a housing (11) that surrounds the pivot pin radially, wholly or partially, such that the pivot pin (8) and the housing (11) can move relative to one another at least by pivoting. A separate retaining element (12; 13), for the housing (11), is associated with the joint device (6). The joint device is designed in such manner that the retaining element (11) starts from an area (14) of the housing (11) and engages in a substantially axial channel (15) of the pin (8).

  • Patent number: 7708488
    Abstract: A joint unit of a control arm of a wheel suspension in a motor vehicle, with a housing (1) and a pivot (2), which is mounted slidingly in the housing by a spheroidal bearing surface (3). The joint unit has a catching device (4) to avoid complete separation of the housing (1) from the pivot (2). The catching device spans over part of the housing (1) in a contactless manner during normal operation. The catching device (4) has at least one flexible catching band or at least one securing strap (4.1, 4.2) with a recess (4.1.1, 4.2.1), into which protrudes a catching pin (1.1, 1.2) of the housing in a contactless manner during normal operation, or at least two securing straps (4.1 and 4.2).
