Abstract
A vehicle seat support comprising two rails extending in a longitudinal direction, a central module slidably mounted on the rails and suitable for supporting the vehicle seat, a footrest slidably mounted on the rails in front of the central module and suitable for receiving the feet of an occupant seated on the seat, a first actuation system able to cause the central module to slide along the rails, and a second actuation system able to cause the footrest to slide along the rails independently of the central module.
Claims22
A vehicle seat support comprising:
- a first rail extending between a rear end and a front end in a longitudinal direction,
- a second rail parallel to the first rail and extending between a rear end and a front end, the first rail and the second rail being intended to be attached to a floor of the vehicle,
- a central module which is slidably mounted on the first rail and second rail and which is suitable for supporting the vehicle seat,
- a footrest slidably mounted on the first rail and second rail between the respective front ends of the first and second rails and the central module, the footrest being suitable for receiving the feet of an occupant seated on the seat,
- a first actuation system able to cause the central module to slide along the first rail and second rail,
- a second actuation system able to cause the footrest to slide along the first rail and second rail independently of the central module, and
- an electronic control device able to control the first and second actuation systems, the electronic control device allowing any one or more of the following configurations:
- a morphological adaptation mode, in which the advancement, respectively the retreat, of the footrest along the rails takes place with a retreat, respectively an advancement, of the seat,
- a preservation mode, in which the advancement, respectively the retreat, of the footrest along the rails takes place with an advancement, respectively a retreat, of the seat, and
- a comfort mode, in which the advancement (respectively the retreat) of the footrest along the rails takes place with a retreat of the seat and a rearward tilting of the backrest of the seat, respectively an advancement of the seat and a forward tilting of the backrest of the seat.
