Adjustable stopper element with improved fixation and/or adjustability

Adjustable stopper device (1) for a vehicle door or hood, comprising:

• a base part (100),
• an adjustment part (200), wherein the adjustment part (200) is connected to the base part (100) via threads (120, 220) and thereby rotatable around a device axis (210) with respect to the base part (100),
• a stopper part (300) configured to contact the vehicle door and to provide an abutment surface (310) for the vehicle door when the vehicle door is closed, wherein the stopper part (300) is connected to the adjustment part (200) and wherein the axial position of the abutment surface (310) is adjustable by turning the adjustment part (200) with respect to the base part (100) around the device axis (210),
• a fastening structure (400) for fastening the base part (100) to the car body (2);
• a rotation snap mechanism, which snaps into distinct rotational angle positions, which comprises:
• a first cylindrical portion (170) in the base part (100), coaxially positioned with the thread (120) of the base part (100), wherein the inner wall of the first cylindrical portion (170) comprises one or more radially inwards protruding teeth or rips or knobs (171), and
• a second cylindrical portion (240) of the adjustment part (200), positioned coaxially with the thread (220) of the adjustment part (200), wherein the outer wall of the second cylindrical portion (240) comprises one or more radially outwards protruding, resilient teeth or rips or knobs (241) which is or are configured to engage with the axially extending teeth or rips or knobs (171) and thereby provide a predefined, resistance to a rotation moment which can be overcome by a predefined threshold moment resulting in a repeated deflection and relaxation of the one or more teeth or rips or knobs (241) of the adjustment part (200) radially inwards and outwards while the adjustment part (200) is being turned around the device axis (210);
• wherein the distal end of the first cylindrical portion (170), which is the end at the far side with respect to the position of the adjustment part (200) and/or stopper part (300), is:
• closed off by the base part's (100) material, or
• covered by a sealing cover (800), formed onto the base part (100) by a two-component injection molding.
