Abstract:
A vehicle seat comprising a base designed to be mounted on a floor of a vehicle, together with a seat proper and a seat back supported by the base, the seat back being pivotally mounted on the base to pivot about a transverse horizontal axis of rotation so that a user can adjust the inclination of said seat back with help of adjustment means, the seat proper extending between a front end and a rear end and having a top face for supporting the user, said seat proper having a mean plane which is substantially parallel to said top face, the seat back having a front face for supporting the user, and said seat back also having a mean plane which is substantially parallel to said front face, the seat having a longitudinal midplane which is perpendicular to the mean planes of the seat proper and of the seat back, the axis of rotation of the seat back being situated in front of the seat back at a first distance from the front face of said seat back as measured in the midplane of the seat parallel to the mean plane of the seat proper, and the axis of rotation of the seat back being situated above the seat proper, at a second distance from the top face of said seat proper as measured in the midplane of the seat parallel to the mean plane of the seat back,the seat being characterized in that the rear end of the seat proper is pivotally mounted on an element secured to the seat back and is supported by said element, andin that the front end of the seat proper is mounted on the base via a linkage adapted to impose angular displacements on the seat proper that are less than half the angular displacements to which the seat back is subjected during adjustment of the inclination of said seat back;wherein the linkage comprises at least one rigid link having a first pivot connected to the base and a second pivot connected to the seat proper, the second pivot being situated above the first pivot; andwherein the first and second pivots are aligned on a direction that forms an angle of less than 20.degree. relative to vertical.
