Pivoting/sliding door for vehicles, comprising at least one door leaf and a spindle drive

Abstract

A pivoting/sliding door for vehicles comprising a door leaf with a support mechanism, a stationary rotatable spindle, and a spindle nut which is connected to the door leaf via a connection element and comprising a stationary guiding rail which has a curved section for a guide element fixed to the door. The curved section is followed by a section which runs perpendicularly to the spindle axis, the connection element is connected to the spindle nut and to a console which is fixed to the door leaf in a pivotal manner about axes, and the door leaf has a closed final position upon reaching the guide element of the transition point between the curved section and the perpendicular section in the longitudinal direction but is preferably still spaced from the closed final position in an adjustment direction.

1 . A pivoting/sliding door for vehicles, the door comprising:
 at least one door leaf;   a support mechanism for the door leaf;   a rotatable spindle arranged in a fixed location in the vehicle and having a spindle axis and a spindle nut, which is connected to the door leaf via a connection element,   wherein the rotatable spindle includes a guide rail, which has a curved section, and is arranged in a fixed location in the vehicle and guides a guide element fixed to the door,   wherein the curved section of the guide rail ( 4 ) is followed by a section which runs perpendicularly to the spindle axis,   wherein the connection element is connected, in such a way as to be pivotable about axes parallel to the spindle axis, both to the spindle nut and to a bracket fixed to the door leaf, and   wherein, when the guide element reaches the transition from the curved section to the perpendicular section, the door leaf has the closed end position in the longitudinal direction.   
     
     
         2 . The pivoting/sliding door of  claim 1 , further comprising a spring acting on the spindle nut in the closing direction. 
     
     
         3 . The pivoting/sliding door of  claim 1 , wherein the curved section of the guide rail has an increasing curvature when viewed in the closing direction. 
     
     
         4 . The pivoting/sliding door, wherein the bracket has components of the support mechanism positioned on the door-leaf side. 
     
     
         5 . The pivoting/sliding door of  claim 1 , wherein, when the door leaf has the closed end position in the longitudinal direction, the door leaf is spaced from the closed end position in an inward movement direction. 
     
     
         6 . The pivoting/sliding door of  claim 2 , wherein the curved section of the guide rail has an increasing curvature when viewed in the closing direction.
