Extensible foot rest
First Claim
1. Extensible foot rest and a seat, said seat having a front edge portion, a pair of side edge portions, and an underside, said underside having a front edge portion below the front edge portion of the seat and a pair of side edge portions below the side edge portions of the seat, a seat mount engaging the underside of said seat between said side edge portions of the underside and offset from said front edge portion of the underside for supporting said seat, said foot rest including a pair of side edge rails and a transverse support member interconnecting said rails and secured to each of said rails, attachment means for attaching said rails to the side edge portions of said underside such that the seat mount extends between said rails and for attaching said transverse support member to said front edge portion of the underside, a pair of sliding brackets slidably mounted on said rails, a foot support pivotally secured to each of said sliding brackets and extending across the front edge portion of the seat, an electric motor mounted on said transverse member, and drive means extending substantially parallel to said rails alongside said mount and connected to said motor and one of said brackets, said brackets sliding along said rails in response to operation of said motor from a retracted position at the front edge portion of the seat to an extended position extended from the front edge portion of the seat to support the feet and legs of the user seated in said seat.

Abstract
An extensible foot rest for a seat of the type used in a van, motor home, or other motor vehicle includes a foot support which is extended and retracted by sliding brackets slidable on rails mounted under the seat. A drive screw is operated by an electric motor to extend and retract the foot support. Pivoting links are provided to rotate the foot support from a generally vertical orientation to a substantially horizontal orientation as the foot support is extended to thereby support the feet and legs of the user seated in the seat.

8. Extensible foot rest and a seat, said seat having a front edge portion and a pair of side edge portions, said foot rest including a support bracket mounted under said seat, said support bracket including a pair of side rails, each of said side rails being mounted under said seat and extending below a corresponding side edge portion of the seat, a pair of sliding brackets slidably mounted on said rails, a foot support secured to each of said sliding brackets and extending across the front edge portion of the seat, and drive means for sliding said sliding brackets along said rails to extend said foot support from a retracted position at the front edge portion of the seat to an extended position extended from the front edge portion of the seat for supporting the feet and legs of the user seated in said seat, said support bracket including a transverse member interconnecting said rails and extending under the front edge portion of the seat, said foot support extending substantially parallel to said transverse member, said drive means including an electric motor mounted on said transverse member, and means for drivingly connecting said electric motor to one of said sliding brackets for sliding said sliding brackets along the rails, said drivingly connecting means including a drive screw extending substantially parallel to said one rail, means for drivingly connecting said drive screw to said motor for rotation thereby, and a drive nut attached to one of said sliding brackets and threadedly connected to said drive screw whereby rotation of said drive screw advances and retracts said drive nut toward and away from said motor, thereby causing said sliding brackets to slide along said rails, said foot support being pivotally mounted on said sliding brackets, and a pair of pivoting links slidably connected to a corresponding one of said sliding brackets, each of said pivoting links being pivotally connected to said foot support and sliding with said sliding brackets as said sliding brackets advance along said rails, said pivoting links pivoting said foot support after moving with the sliding brackets for a predetermined distance without pivoting said foot support.
