Definitions

  • the invention relates to a door handle for motor vehicles according to the preamble of patent claim 1.
  • Such a door handle is known from DE 26 58 159 B2.
  • an actuating lever is provided there, in which the return to the starting position required after actuation takes place automatically via spring forces and is limited by a fixed stop.
  • An elastic intermediate layer forms a damping pad for the limit stops in order to reduce the noise that occurs when the spring-loaded operating lever strikes the stops.
  • Such and similar passive, elastic damping pads for a low-noise return of an operating lever are used in various ways.
  • the intended damping path is very short and exact positioning is difficult due to the tolerances and material fatigue.
  • due to their elastic properties, such materials do not allow the operating lever to be returned smoothly and smoothly to its starting position. The impact noise is thus only incompletely and unreliably reduced.
  • the invention has for its object to design a door handle of the type mentioned so that an extensive and reliable reduction of the impact noise is achieved.
  • the characterizing features of claim 1 are provided in a door handle of the type mentioned.
  • the actuating lever is coupled to a damping element during its return movement from a certain position until it reaches its starting position in such a way that this exerts a force on the actuating lever which is opposite to the spring force, which is greater than a certain, low speed of the actuating lever the spring force is.
  • the characteristic feature according to claim 3 offers the advantage that the actuation of the closing mechanism by the actuating lever is possible without being influenced by the damping element.
  • the features of claim 6 advantageously enable a damped guidance of the actuating lever even from the starting position, which reduces the risk of damage to parts connected to the actuating lever due to jerky actuation.
  • FIG. 1 shows a door actuation mechanism which is damped according to the invention.
  • An outer door handle not shown in more detail, which is pivotably mounted at one end, engages at the other end via the extension (17) through the door wall and is at the end (4) of the extension (17) a lever (5) articulated.
  • the lever (5) is rotatably supported by the axis (2) and has an extension (6) which is fixedly connected to it and serves as a mass balance weight.
  • the axis (2) like another axis (10), is mounted vertically on two parallel, horizontally running retaining plates, between which the lever (5) is located, only the lower retaining plate (1) being shown in the section of the drawing .
  • the lever (5) After operating the outer door handle, the lever (5) is in a position rotated counter to the direction of the arrow shown. After releasing the outer door handle, the spring (7) a return movement in the direction of the arrow shown via the lever (5). This takes place initially without the action of the damping element (11), the locking mechanism (not shown here) coupled to the outside door handle via the rod (16) being actuated in this movement phase. Before the lever (5) reaches its end position shown, the extension (6) engages in a recess (14) in the damping element (11) and carries it in a rotational movement about the axis (10).
  • the damping element (11) exerts a force, which is dependent on its angular velocity, on the extension (6), which brakes the rotary movement of the lever (5) caused by the spring (7).
  • the system reaches its end position at low speed with a relatively long braking distance compared to elastic damping pads, which enables effective noise reduction.
  • the damping element (11) is reset again via the extension (6) which engages in the recess (14). This also prevents jerky lever actuation that is damaging to the material.
  • the damping element (11) can be designed as shown in FIG. 2. It consists of a cylinder-like sleeve that has a bottom and a cover and is rotatably mounted on the shaft (10) that is passed through. A recess (14) is arranged in the circular cylindrical outer wall (22). The externally sealed cavity (20) inside the sleeve is filled with a liquid of suitable viscosity. Rectangular wing plates (18, 19, 23), which are designed as perforated plates, are attached to the fixed axis (10) in the cavity (20). A corresponding wing plate (21) is firmly connected to the outer wall (22). When the outer wall rotates (22) relative to the fixed axis (10) the liquid must flow through the openings in the perforated plates. As is known, the resistance force exerted by the viscosity of the liquid increases with increasing relative speed. The damping element therefore exerts the desired speed-dependent damping force on the extension (6).

Claims (8)

  1. Poignée de porte pour véhicules automobiles, qui possède un levier d'actionnement (5) pour actionner un dispositif de fermeture d'une porte de véhicule, dont le mouvement de retour à la position de départ se produit sous l'action de forces élastiques, et est limité par une butée (13a), cependant qu'il est prévu des moyens d'atténuation du bruit,
    caractérisée
    en ce qu'un de ces moyens est un élément amortisseur mobile (11) qui peut être accouplé au levier d'actionnement (5) au moins peu de temps avant l'arrivée à sa position de départ, et exerce sur lui une force dirigée en sens inverse de la force élastique, qui décroît avec la décroissance de la vitesse du levier d'actionnement (5), et reste plus grande que la force élastique jusque peu de temps avant l'arrivée à la position de départ, l'élément amortisseur (11) produisant la force de ralentissement fonction de la vitesse sous l'action d'un effet de viscosité.
  2. Poignée de porte selon la revendication 1,
    caractérisée
    en ce que, sur un segment partiel de l'ensemble de la course de retour du levier d'actionnement (5), il n'y a pas de liaison entre l'élément amortisseur (11) et le levier d'actionnement (5).
  3. Poignée de porte selon la revendication 1 ou 2,
    caractérisée
    en ce que l'élément amortisseur (11) est monté rotatif.

  5. Poignée de porte selon la revendication 3 ou 4,
    caractérisée
    en ce que l'élément amortisseur (11) présente, sur sa circonférence, une échancrure (14) dans laquelle s'engage le levier d'actionnement (5) ou un prolongement (6) solidaire de ce levier.
  6. Poignée de porte selon la revendication 5,
    caractérisée
    en ce que le levier d'actionnement (5) ou le prolongement (6) s'engage dans l'échancrure (14) dans les deux sens de rotation de l'élément amortisseur (11).
  7. Poignée de porte selon une ou plusieurs des revendications 1 à 6,
    caractérisée
    en ce que la butée (13a) de limitation du mouvement de retour attaque l'élément amortisseur (11).
