Embodiment Construction

[0054] In the following description, when referring to absolute position qualifiers, such as the terms "front", "rear", "top", "bottom", "left", "right", etc., or relative positions, such as the term "above" , "below", "upper", "lower", etc., or directional qualifiers, such as "horizontal", "vertical", etc., unless otherwise stated, refer to the orientation in the drawing or when the seat is in the normal use position orientation.

[0055] In the rest, the longitudinal direction X denotes the longitudinal direction of the seat. The longitudinal direction of the seat is considered to be the same as the longitudinal direction of the motor vehicle on which the seat is installed. This longitudinal direction X corresponds to the normal direction of the forward motion of the vehicle. The longitudinal direction X is preferably horizontal. The transverse direction Y is the transverse direction of the seat. Thus, the transverse direction of the seat corresponds to the transverse or...

Abstract

A vehicle seat (1) comprises a seat-bottom frame (3); a seatback frame (2) comprising at least one first lateral riser (21) mounted pivoting relative to said seat-bottom frame (3) around a transverse axis (Y1); a first discontinuous type hinge mechanism (4) with a first side-plate rigidly fixed to the seat-bottom frame (3) and a second side-plate; an intermediate riser mounted on the seat bottom frame (3), pivoting around the transverse axis (Y1), by means of the first hinge mechanism (4) where the intermediate riser and the second side-plate are securely connected in rotation around the transverse axis (Y1); where the intermediate riser is fixed to the first lateral riser (21) at a distance from the transverse axis (Y1); where the intermediate riser has a stiffness less than the stiffness of the first lateral riser (21) of the seatback frame (2).

Description

technical field [0001] The present disclosure relates to the field of vehicle seats, in particular seats for automobiles. Background technique [0002] Vehicle seats, especially for automobiles, usually comprise a backrest whose inclination relative to the seat bottom is adjustable about an axis by means of a hinge system comprising one or two hinge mechanisms. Each hinge mechanism includes a first side panel and a second side panel, wherein each side panel is firmly connected to the seat bottom frame and the seat back frame. [0003] Two types of hinge mechanisms are known, in particular continuous and discontinuous. [0004] A continuous hinge mechanism, usually comprising a cycloid arrangement, allows locking of the first side panel relative to the second side panel at any relative angular position of the seat back relative to the seat bottom. [0005] Discrete hinge mechanisms typically include a locking element that is radially movable relative to a ring gear. In the...
