  • Patent number: 11673529
    Abstract: A vehicle seat having at least one buckle for receiving a safety belt on a first lateral side of the seat and an attachment of the end of a pelvic strap of the safety belt on a second lateral side of the seat. The seat includes at least one safety device, each safety device having a first cable connecting the buckle or the attachment of the end of the pelvic strap to a first anchor point, and at least one second cable connecting the buckle or the attachment of the end of the pelvic strap to a second anchor point traction on the second cable resulting in a general movement of the buckle or attachment of the pelvic strap end eliminating the risk of submarining.

  • Publication number: 20210362633
    Abstract: A vehicle seat having a seat cushion and a sliding rail, the seat cushion being movable in an elevation direction. The seat includes an anchoring element and a holding device, with the holding device having a cam and a blocking element. The blocking element is mounted so as to be movable at least in rotation between a nominal position and a blocking position so as to prevent the movement of the seat cushion. The cam is mounted so as to be movable between a rest position and an active position in which it drives the blocking element toward its blocking position. The cam is configured to be moved to the active position when a force greater than a predetermined force is applied to the anchoring element.

  • Publication number: 20210339657
    Abstract: A vehicle seat that includes: a cushion; a backrest; an articulation having a first flange fixed to the cushion and a second flange fixed to the backrest, the second flange being mounted so as to be able to rotate with respect to the first flange; a device for straightening the backrest interdependently rotating with the second flange and defining a straightening slot comprising a first portion separated from a second portion by a bridge; and a pin integral with the backrest, extending into the first portion of the straightening slot. When an impact torque greater than a predetermined torque is applied to the backrest, the pin breaches the bridge and then moves freely in the second portion.

  • Patent number: 10875433
    Abstract: The present disclosure relates to a vehicle seat comprising a seating portion, a backrest with a front face and which extends in a main direction Z and which has a hole for the upward exit of a seat belt from the backrest and a support which the seat belt bears against in order to descend along the front face of the backrest, and a headrest mounted on the backrest and slidable relative to the rest of the backrest along the main direction Z. The support is slidable relative to the rest of the backrest along the main direction Z, and the seat comprises a drive mechanism capable of simultaneously causing the headrest to slide along the main direction for a first amplitude A1 and the support for a second amplitude A2 different from the first amplitude A1, and an actuator able to actuate the drive mechanism.

  • Patent number: 10549654
    Abstract: A vehicle seat having a pivoting function about a vertical axis (Z1). The seat includes a base configured for connection to the floor (PL) of the vehicle via longitudinal rails, a support frame mounted so as to rotate on the base by means of a pivot joint (JP) of axis Z1 and three curved slide connections (G1,G2,G3), a seating portion frame connected to the support frame directly or via a raising mechanism, and a motorization device interposed between the base and the support frame and configured to cause rotational movement of the support frame relative to the base. The axis Z1 of the pivot joint is eccentric with respect to a central area of the seating portion frame.
