Abstract
The invention relates to a window blind for a sliding roof system includes a flexible material and two flat spiral springs that extend along the longitudinal edges of the window blind. The flat spiral springs tend to contract into a spiral shape, winding the flexible material into a coil.
Claims17
A window blind for a sliding roof system, comprising:
- a flexible material having two longitudinal edges;
- and
- at least one spring strip extending along at least one of the two longitudinal edges and having a biasing force tending to contract the spring strip into a spiral, wherein the at least one spring strip has an inboard edge and an outboard edge, the flexible material being attached only from the outboard edge to a vertex of the at least one spring strip such that the inboard edge is spaced from the flexible material.
A vehicle roof blind assembly, comprising:
- two guide rails;
- a flexible material having two longitudinal edges;
- and
- two spring strips, each spring strip received in one of the two guide rails and fixed along one of the two longitudinal edges, with each spring strip having an inboard edge and an outboard edge wherein the flexible material is only attached from the outboard edge to a vertex of each spring strip such that each inboard edge is spaced from the flexible material, and
- wherein each spring strip has a biasing force tending to contract the spring strip into a spiral such that each spring strip winds a portion of a window blind extending outside of the two guide rails into a coil.

A vehicle roof blind assembly for a sliding roof system, comprising:
- a blind selectively moveable to cover a roof opening, the blind being formed from a flexible material having two longitudinal edges;
- at least one spring strip extending along at least one of the two longitudinal edges and having a biasing force tending to contract the at least one spring strip into a spiral, the at least one spring strip having an innermost spring edge and an outermost spring edge, and wherein the at least one spring strip is attached to one of the two longitudinal edges of the flexible material only from the outermost spring edge to a vertex of the at least one spring strip;
- and
- at least one guide rail mountable to a vehicle roof adjacent the roof opening, the at least one guide rail guiding movement of the blind between an open position and a closed position relative to the roof opening.
