Supporting device for sliding door

Abstract

The present invention provides a support device for a sliding door, which can be applied to various types of vehicles. A bracket (21) is provided which is fixed to the sliding door, and a first arm (23) is pivotally supported on the sliding door so as to be rotatable in the vertical direction through a first pivot shaft (22) parallel to the opening and closing direction of the sliding door. a bracket (21); a second arm (24), supported so as to be relatively movable in the left-right direction with respect to the first arm (23), and rotatable in the up-down direction integrally with the first arm (23); The guide pulley (25) is rotatable around a shaft (251) facing the up-down direction on the second arm (24) and can move along the guide rail.

Description

technical field [0001] The present invention relates to a support device for a sliding door for supporting a sliding door on a vehicle body in an openable and closable manner. Background technique [0002] SUV vehicles (multi-purpose passenger vehicles) often use a style in which the roof slopes down slightly toward the rear and curves toward the center of the body. As a result, the outside of the roof rail in the rear portion of the periphery of the roof similarly assumes a three-dimensional shape that slopes slightly downward toward the rear and is curved toward the center of the vehicle body. In addition, the rear door is a swing-type door in which the front end portion is pivotally supported so as to be rotatable about an axis in the vertical direction. [0003] Therefore, getting into and out of the rear seat of the SUV car is performed by opening and closing the swing-type rear door, but when getting in and out, it has to be performed from the vicinity of the rear end...

Problems solved by technology

[0007] However, in a vehicle with a body shape such as an SUV, the outside of the roof rail and the upper edge of the rear door have a three-dimensional shape as described above, so the upper rail attached to the outside of the roof rail has to also have a three-dimensional shape.

[0008] On the other hand, the waist rail and the lower rail have a two-dimensional shape in the vehicle width direction, so the positional relationship between the three-dimensional upper rail and the upper pulley unit is along the vertical direction and the vehicle width direction as the opening and closing position of the sliding door changes. Therefore, the upper guide pulley unit described in Patent Document 1 and other known upper guide pulley units (supporting devices for sliding doors) cannot be applied.
