Abstract: A system for a vehicle seat includes: a functional device able to selectively occupy Np states, where Np is a positive integer; an input interface configured for collecting Nm parameters, where Nm is a positive integer, related to the vehicle and/or to the seat and/or to a user of the seat; a control device configured for changing the functional device from one of the Np states to another of the Np states; a control interface enabling the user to set the functional device, via the control device, to the state to be in; and a data storage unit. The system is configured for sending the values of the Nm parameters to the data storage unit each time the user places the functional device in one of the Np states.

Abstract: A motor vehicle control case includes an outer shell with several control areas, each of the control areas assigned to a specific function of the vehicle, a printed circuit board supporting elementary sensors to generate an electrical signal in response to an action such as an approach movement, a contact or a pressure exerted by a user by having his fingers on at least one of the control areas. The elementary sensors are connected to an electronic control unit, the electrical signal generated by the elementary sensors being transmitted to the electronic control unit to be analyzed therein and converted into a control of a function of the vehicle. Each elementary sensor includes at least one insulating substrate on which are deposited conductive tracks forming a capacitive sensor and an assembly of conductive or semi-conductive nanoparticles in colloidal suspension in an electrically insulating ligand, the assembly forming a force sensor.

Abstract: A headrest assembly for a vehicle seat, that is height-adjustable along an adjustment direction. The headrest assembly includes a pin adapted to be fixed to a seat backrest and extending along the adjustment direction, an adjustment plate integrally secured to the one pin, and a supporting structure adapted to support a user's head, mounted so as to be adjustable in translation on the adjustment plate along the adjustment direction. The pin is covered by a covering portion. The covering portion and the adjustment plate are made of plastic material overmolded on the pin.

Abstract: A rack of molded plastic having a series of notches open in a first direction, each notch having a certain width in a second direction perpendicular to the first direction. The notches are aligned in a third direction perpendicular to the first and second directions, and each notch is defined by a bottom and by first and second side walls extending in the first direction from the bottom to a mouth of the notch. A rib projects into each notch from the first side wall, and the bottom of the notch has a through-opening arranged in correspondence with the rib.

Abstract: A headrest assembly for a vehicle seat includes two pins each extending along an adjustment direction between a lower end and an upper end, each of the two pins having a mounting portion comprising the lower end and adapted to be fixed to a backrest of a seat, an adjustment portion comprising the upper end, and an intermediate portion between the mounting portion and the adjustment portion. The seat further includes a support structure adapted to support the head of a user, and an interface made of overmolded plastic and interconnecting the intermediate portions of the two pins.

Abstract: A cover element for a motor vehicle seat element lining, including: a foam on the reverse side of a textile, skin, or synthetic material; and in edges, intended to be assembled by sewing to at least one piece of textile, skin, or synthetic material, one or a plurality of embossed notches forming alignment marks to perform the sewing.

Abstract: An adjustable headrest for motor vehicle seat. The headrest includes a support structure fixed to a backrest and a body having a front shell and a rear shell. The front shell has a front face intended for contact with the head of a user of the seat, the front face being movable relative to the support structure along a front-rear direction denoted X, over a total travel distance. The total travel distance is formed by a first travel portion provided by a mounting enabling translational movement of the body relative to the support structure while maintaining the position of the front shell relative to the rear shell substantially constant. The total travel distance is also formed by a second travel portion provided by a mounting enabling translational movement of the front shell alone relative to the rear shell.
