Embodiment Construction

[0025] now refer to figure 1 , the vehicle 10 has a sliding door 11 supported along an upper roller track 12 , a lower roller track 13 and a center roller track 14 . A corresponding roller bracket (not shown) slidable in each track is combined with a corresponding door bracket (not shown) on the inner side of the sliding door 11 . In a conventional system, a pair of brackets at the top and bottom of the front edge of the sliding door 11 are combined with roller brackets sliding in the tracks 12 and 13 respectively. A door bracket attached at the central rear edge of the sliding door 11 is connected with a roller bracket slidably received in the track 14 . The track has an initial portion that moves radially outward so that the door first moves outwardly from the body to clear the body, and then slides toward the rear of the vehicle 10 . Due to this compound movement, each roller bracket is pivotally connected to its corresponding door bracket.

[0026] The sliding door 11 a...

Abstract

The invention relates to extended-travel sliding door with articulating roller bracket. A sliding door for a vehicle has a door bracket. A track is mounted along the vehicle and extends to a remote end. A roller bracket is movable between a first position proximate the opening and a second position at the end of the track. The roller bracket includes an articulating arm retained by the roller bracket by a first pivot and pivotally retained at a second end by the door bracket. The articulating arm has a first orientation for rotationally positioning the sliding door toward the closed position and a second orientation for rotationally positioning the sliding door into the open position. Movement of the roller bearing into the second position results in the articulating arm moving from the first to the second orientation. An over-center spring mechanism may maintain the positioning of the roller bracket relative to the sliding door throughout the travel of the bracket.

Description

technical field [0001] The present invention generally relates to a sliding door for a vehicle, wherein the rear side of the sliding door is supported by roller brackets which pass over roller tracks mounted along the outside of the vehicle. Background technique [0002] A representative sliding door for a passenger vehicle such as a van, minivan, or crossover vehicle is supported by upper and lower track assemblies at the leading edge of the sliding door and a center track assembly attached to the rear edge of the door and boot. [0003] The size of the uncovered door opening when the sliding door is open is limited by the effective distance of rearward travel of the door. Large door openings are desirable for ease of entry / exit and to maximize the size of the load passing through the door opening. However, door travel is typically limited by the length of the track in which the roller bracket assembly passes during opening of the sliding door. The center rail that recei...
