Magnetic header design

1. A sunshade for a vehicle top, said vehicle top spans a portion of the vehicle from a rear weatherproof top portion to a front portion with an opening over a front passenger compartment, said opening extending to a windshield header of the vehicle, the sunshade comprising:

an air penetrable flexible membrane cover portion for covering above the opening over the front passenger compartment of the vehicle, said membrane cover portion having a forward edge; and

at least one magnetic portion at the forward edge of the membrane cover portion for providing secure releasable attachment of the sunshade to the windshield header of the vehicle said magnetic portion being supported in an elongated transverse rigid structural member, said magnetic portion having a spherical male/female magnetic force interface engagement with said windshield header.

2. The sunshade of claim 1 further comprising said windshield header having a longitudinally extending latch plate wherein said magnetic portion is configured to engage said latch plate.

3. The sunshade of claim 1 wherein said membrane cover portion is a mesh-like material.

4. The sunshade of claim 2 wherein said magnetic portion includes a first portion for connecting and engaging said windshield header substantially vertically along said spherical male/female interface and a second portion for horizontally engaging said latch plate along a vertical interface.

5. The sunshade of claim 1 wherein said magnetic portion is at least partially fabricated with a magnetic polymer.

6. A vehicle arrangement comprising:

a vehicle body with a front transverse window with a ferromagnetic frame header and a front passenger compartment;

a top with a rear weatherproof portion and a front portion with an opening over the front passenger compartment, said opening extending to the windshield header of the vehicle an air penetrable flexible membrane cover portion for covering above the opening over the front passenger compartment of the vehicle, said membrane cover portion having a forward edge; and

at least one magnetic portion at the forward edge of the membrane cover portion for providing secure releasable attachment of the sunshade to the windshield header of the vehicle said magnetic portion being supported in an elongated transverse rigid structural member, said magnetic portion having a spherical male/female magnetic force interface engagement with said windshield header.

7. A vehicle arrangement as described in claim, 6 wherein said magnetic portion tensions said flexible member.

8. A vehicle arrangement as described in claim 6 , wherein the arrangement has a latch plate fixed with respect to said frame for a rigid top and the latch plate acts as a stop for said magnetic portion in the longitudinal direction.

9. A vehicle arrangement as described in claim 8 , wherein an interface between the magnetic portion and said latch plate acts as a stop in a transverse vehicle direction.

10. A vehicle arrangement as described in claim 9 with a plurality of latch plates acting as stops in a transverse vehicle direction.

11. A vehicle arrangement as described in claim 6 , wherein said magnetic portion has a plurality of discrete magnets.

12. A vehicle arrangement as described in claim 6 , wherein said magnetic portion has a magnet embedded in a non-magnetic material.

13. A vehicle arrangement as described in claim 6 , wherein magnetic member is connected with a sealing material to seal an interface between said magnetic portion and said window frame.

14. A vehicle arrangement as described in claim 6 , wherein said magnetic portion can be moved longitudinally on the vehicle to a plurality of positions.

15. A vehicle arrangement as described in claim 6 , wherein the vehicle is a sport utility-type vehicle.
