Abstract

A display assembly for an automotive interior comprises a dynamically bendable cover panel having first and second panel portions a flexible panel portion connecting the first and second panel portions, a display positioned adjacent the first and second panel portions, and a frame that supports the cover panel and comprises a first frame portion for supporting the first panel portion, a second frame portion for supporting the second panel portion, and a hinge portion coupling the first frame portion and the second frame portion, the hinge portion configured to induce a curvature having smoothly connected arc segments in the flexible panel portion between the first panel portion and the second panel portion when the second frame portion is articulated relative to the first frame portion from a straight position to a deployed position.

First claim

We claim:

1. A display assembly for an automotive interior, the display assembly comprising:
a dynamically bendable cover panel comprising:
a first panel portion;
a second panel portion; and
a flexible panel portion connecting the first panel portion and the second panel portion;

a display adjacent the first panel portion and the second panel portion; and
a frame supporting the dynamically bendable cover panel, the frame comprising:
a first frame portion for supporting the first panel portion;
a second frame portion for supporting the second panel portion; and
a hinge portion coupling the first frame portion and the second frame portion, the hinge portion configured to induce a curvature having smoothly connected arc segments in the flexible panel portion between the first panel portion and the second panel portion when the second frame portion is articulated relative to the first frame portion from a straight position to a deployed position, wherein:
the hinge portion comprises a living hinge,
the living hinge comprises a mechanical weakening of the frame in the hinge portion, and
the living hinge comprises a plurality of longitudinal slots extending across the hinge portion proximate the flexible panel portion.

2. The display assembly of claim 1 , wherein each of the plurality of longitudinal slots comprises:
a flat trough extending parallel to the flexible panel portion; and
abutment surfaces extending from the flat trough, wherein a spacing between the abutment surfaces is smaller than a width of the flat trough when the hinge portion is in the straight position.

3. The display assembly of claim 1 , wherein each of the plurality of longitudinal slots comprises overhanging flex arresters.

4. The display assembly of claim 3 , wherein the overhanging flex arrestors comprise:
a first projection extending transversely from the hinge portion;
a second projection extending transversely from the hinge portion spaced from the first projection;
a cross member extending longitudinally from the second projection spaced from the hinge portion; and
a tab extending transversely from the cross member toward the hinge portion on an opposite side of the first projection as the second projection.

5. A display assembly comprising:
a dynamically bendable cover panel comprising:
a first panel portion;
a second panel portion; and
a flexible panel portion connecting the first panel portion and the second panel portion;

a display adjacent the first panel portion and the second panel portion; and
a frame supporting the dynamically bendable cover panel, the frame comprising:
a first frame portion for supporting the first panel portion;
a second frame portion for supporting the second panel portion; and
a hinge portion coupling the first frame portion and the second frame portion, the hinge portion configured to induce a curvature having smoothly connected arc segments in the flexible panel portion between the first panel portion and the second panel portion when the second frame portion is articulated relative to the first frame portion from a straight position to a deployed position; and

a mandrel having the shape of the circular arc segment, wherein:
the hinge portion of the frame comprises the mandrel, or
the first frame portion, the second frame portion and the hinge portion of the frame are a monolithic structure and the mandrel is positioned behind the hinge portion.

6. The display assembly of claim 5 , wherein the second frame portion is slidable relative to the second panel portion and includes a surface configured to mate flush with the mandrel such that when the second panel portion is slid into engagement with the mandrel the frame is in the straight position and when the second panel portion is slid out of engagement with the mandrel the frame is in the deployed position.

7. A display assembly comprising:
a dynamically bendable cover panel comprising:
a first panel portion;
a second panel portion; and
a flexible panel portion connecting the first panel portion and the second panel portion;

a display adjacent the first panel portion and the second panel portion; and
a frame supporting the dynamically bendable cover panel, the frame comprising:
a first frame portion for supporting the first panel portion;
a second frame portion for supporting the second panel portion; and
a hinge portion coupling the first frame portion and the second frame portion, the hinge portion configured to induce a curvature having smoothly connected arc segments in the flexible panel portion between the first panel portion and the second panel portion when the second frame portion is articulated relative to the first frame portion from a straight position to a deployed position, wherein the hinge portion comprises a plurality of hinge linkages pinned to the first frame portion and the second frame portion.

8. The display assembly of claim 7 , wherein the plurality of hinge linkages comprises an elongate, curved linkage having a first end pinned to the first frame portion, a middle member configured to extend across the flexible panel portion and at least a portion of the second panel portion, and a second end pinned to the second frame portion at a slot, wherein the second frame portion extends over only a portion of the second panel portion.

9. The display assembly of claim 8 , wherein the elongate curved linkage is configured to engage the flexible panel portion in the deployed position and disengage from the flexible panel portion in the straight position.

10. The display assembly of claim 7 , wherein the plurality of hinge linkages comprises:
a curved linkage pinned to the first frame portion, extending across the flexible panel portion and pinned to the second frame portion at a slot;
a first straight boss rigidly extending from the first panel portion at least partially across the flexible panel portion; and
a second straight boss rigidly extending from the second panel portion at least partially across the flexible panel portion;
wherein in the straight position, the first and second straight bosses engage the flexible panel portion and in the deployed position the curved linkage engages the flexible panel portion.

11. The display assembly of claim 7 , wherein the plurality of hinge linkages comprises a scissor mechanism, wherein the scissor mechanism comprises:
a plurality of posts extending from behind the flexible panel portion, each of the plurality of posts having a pivot point at a free end thereof;
a plurality of first linkages extending from the pivot points at a first end and joined to an adjacent first linkage at a second end; and

a plurality of second linkages extending from the second ends of the first linkages at a third end and joined to an adjacent second linkage at a fourth end.

12. The display assembly of claim 1 , further comprising a damper to control movement of the hinge portion between the straight and deployed positions, wherein the damper is selected from the group consisting of a hydraulic dashpot, a spring, a crumple device and a rubber stopper.

13. The display assembly of claim 1 , wherein the hinge portion is configured to induce a radius of curvature having a circular arc segment in the flexible panel portion between the first panel portion and the second panel portion.
