Abstract
A buckle device for a car seatbelt system is used together with a plurality of tongue plates to which occupant securing webbings are connected. Lock members for engaging the tongue plates are released upon operating a single release button. The shifting direction of the release button is confined in a plane defined by the insertion directions of the tongue plates. The operation force of the release button is transmitted to the lock members via a mechanism for example cam-contact or link mechanism. Therefore, the operation necessary for a passenger at the time of release is only to push the release button. There is no need to hold or pinch the buckle device at any time.
Claims21
A buckle device in which a plurality of tongue plates are inserted and engaged therein, comprising:
- a buckle body supported to a vehicle body;
- lock members being reciprocally movable between an engagement position and a disengagement position for the corresponding tongue plate in a plane defined by the insertion directions of the tongue plates and being supported in the buckle body which come into engagement with the corresponding tongue plates;
- an urging means for urging the lock members to the engagement position;
- and
- a release button movable relative with respect to the buckle body, and being able to contact and to operate transversely with the lock members to bring the lock members out of engagement with the corresponding tongue plates, the relative movement of the release button being confined in the plane defined by the insertion directions of the tongue plates,
- whereby the lock members can be released through a sliding operation of the release button by an occupant.
A buckle device for retaining two tongue plates with occupant fastening webbings connected thereto, comprising:
- a buckle body supported to a body of a vehicle via a compressive force supporting member;
- a plurality of paths for the insertion of a plurality of tongue plates which are formed in the buckle body in mutually crossing directions;
- a plurality of lock bars being reciprocally movable between an engagement position and a disengagement position for the corresponding tongue plate in a plane defined by the insertion directions of the tongue plates and, being supported in the buckle body which come into engagement with notches of the tongue plates inserted to engage the tongue plates;
- an urging means for urging the lock bar to the engagement position;
- and
- a release button movable, upon receipt of an operation force from an occupant, relative with respect to the buckle body and being able to contact and operate transversely with the lock bars to come into cam-like engagement with the two lock bars to thereby separate the lock bars from the notches of the tongue plates.
A buckle device for retaining a plurality of tongue plates to which occupant securing webbings are connected, comprising:
- a buckle body supported to a body of a vehicle via a compressive force supporting member;
- a plurality of paths for the insertion of each tongue plate which are formed in the buckle body in mutually crossing directions;
- lock members being reciprocally movable between an engagement position and a disengagement position for the corresponding tongue plate in a plane defined by the insertion directions of the tongue plates and, being supported in the buckle body which come into engagement with notches of two tongue plates inserted to engage each tongue plate;
- an urging means for urging the lock members to the engagement position;
- a release button disposed movable in a direction midway between the insertion paths of the tongue plates in a plane defined by the insertion paths, which is pressing operation by a passenger;
- and
- a link mechanism inclusive of links for transmitting the pressing force of the release button to the lock members to transversely separate the lock members from the tongue plates, one end of each of the links being movable in the moving direction of the release button and another end in the separating direction of the lock members from the tongue plates.
A buckle device for retaining a plurality of tongue plates to which occupant securing webbings are connected, comprising:
- a buckle body supported to a body of a vehicle via a compressive force supporting member;
- a plurality of paths for the insertion of each tongue plate which are formed in the buckle body in mutually crossing directions;
- lock members supported in the buckle body which come into engagement with notches of two tongue plates inserted to engage each tongue plate;
- a release button disposed movable in a direction midway between the insertion paths of the tongue plates in a plane defined by the insertion paths, which is pressing operation by a passenger;
- and
- a link mechanism inclusive of links for transmitting the pressing force of the release button to the lock members to separate the lock members from the tongue plates, one end of each of the links being movable in the moving direction of the release button and another end in the separating direction of the lock members from the tongue plates wherein the link mechanism includes four links of identical length arranged in the form of a parallelogram.
A buckle device in which a plurality of tongue plates are inserted and engaged therein, comprising:
- a buckle body supported to a vehicle body;
- lock members being reciprocally movable between an engagement position and a disengagement position for the corresponding tongue plate in a plane defined by the insertion directions of the tongue plates and being supported in the buckle body which come into engagement with the corresponding tongue plates;
- and
- a release button movable relative with respect to the buckle body, and being able to contact and to operate transversely with the lock members to bring the lock members out of engagement with the corresponding tongue plates, the relative movement of the release button being confined in the plane defined by the insertion directions of the tongue plates.
