Support element system for elevators

A support element system for elevators, comprising:

• at least one support element having exactly two load-bearing tensile carriers, which are arranged in a horizontal orientation adjacent to one another and which are enclosed in a common elastomeric casing separating the two tensile carriers, wherein the tensile carriers respectively have an opposite direction of wrap, wherein a maximum width and a maximum height of a cross-section of the support element has a ratio of substantially 1:1, wherein a vertical orientation of the tensile carriers is to half the maximum height of the cross-section of the support element, the support element having two spaced apart planar traction surface regions extending in a longitudinal direction of the support element, each of the traction surface regions extending in a single plane angled relative to the vertical and horizontal orientations of the tensile carriers in the support element cross-section, and the traction surface regions connected by a lower side surface that is at least in part not angled relative to the vertical and horizontal orientations of the tensile carriers in the support element cross-section;
• and
• a drive pulley for transmission of a drive force to the at least one support element, wherein the drive pulley has a contoured traction surface with two spaced apart support surfaces which are provided for transmission of the drive force and which co-operate with the planar traction surface regions of the support element to transmit the entire drive force from the drive pulley to the support element, the drive pulley contoured traction surface extending between the support surfaces being spaced from and not contacting an entirety of the lower side surface of the support element when each of the two traction surface regions is in contact with an associated one of the support surfaces.
