Combination pickup truck liftgate/tailgate
View Patent ↗A liftgate/tailgate assembly for a vehicle having a chassis and a cargo area, such cargo area comprising a bed and one or more vertical sidewalls mounted to the vehicle chassis, such liftgate/tailgate assembly comprising a tailgate which, when rotated into an open tailgate position, forms a liftgate/tailgate platform to support a load to be lifted, and one or more linkage assemblies pivotably mounted to the tailgate which permit the liftgate/tailgate platform to be translated both vertically and horizontally relative to the cargo area of the vehicle, while permitting rear impact protection to be mounted on the vehicle and method for lifting a load into a vehicle cargo area.
1. A liftgate/tailgate assembly for a vehicle having a chassis and a cargo area, such cargo area comprising a bed and one or more vertical sidewalls mounted to the vehicle chassis, such liftgate/tailgate assembly comprising
(a) a tailgate which, when rotated into an open tailgate position, forms a liftgate/tailgate platform to support a load to be lifted;
(b) one or more linkage assemblies pivotably mounted to the tailgate which permit the liftgate/tailgate platform to be translated both vertically and horizontally relative to the cargo area of the vehicle;
(c) rear impact protection mounted on the vehicle or on one or more of the liftgate/tailgate linkage assemblies, such that the rear impact protection is directly adjacent to the tailgate when the tailgate is in a closed position wherein the rear impact protection is attached directly to one or more of the linkage assemblies, and to no other portion of the vehicle.
2. The liftgate/tailgate assembly of claim 1 Wherein the rear impact protection is attached to one or more crosslink(s) of the linkage assemblies.
3. The liftgate/tailgate assembly of claim 1 or 2 wherein a portion of the rear impact protection abuts structural members connected to the vehicle chassis only when the liftgate/tailgate assembly is in a closed position.
4. A method for lifting a load into the cargo area of a vehicle while maintaining at least some rear impact protection, such vehicle having a chassis, a rear bumper beam, and a cargo area comprising a bed mounted to the vehicle chassis and one or more vertical sidewalls, such method comprising
(a) pivotably mounting a tailgate to a movable vertical link, and translating the vertical link, and the associated tailgate, from a lowered position, both vertically and horizontally, with one or more cross-links, to align the tailgate with the bed of the cargo area of the vehicle;
(b) mounting the rear bumper beam to one or more of the linkage assemblies, but not to any other part of the vehicle;
(c) positioning structural members that are connected to the vehicle chassis so that they abut a portion of the rear bumper beam when the tailgate is in a closed position and form part of the rear impact protection of the vehicle.
