MOUNTABLE SKYLIGHT ASSEMBLY AND INSTALLATION THEREOF

1 . A skylight assembly for a vehicle, the skylight assembly comprising:

a first portion comprising a lens and a first annular wall defining a central axis and having at least one securing tab; and

a second portion comprising a second annular wall having at least one detent configured to engage with at least a portion of the at least one securing tab.

2 . The skylight assembly of claim 1 , wherein the at least one securing tab comprises a protrusion and the at least one detent comprises a ramped surface and a retention surface for engaging with the protrusion.

3 . The skylight assembly of claim 1 , wherein the at least one securing tab is a plurality of securing tabs coaxial with the central axis and the at least one detent is a plurality of detents coaxial with the central axis.

4 . The skylight assembly of claim 1 , wherein the first annular wall comprises a torque limiting member having an aperture coaxial with the central axis.

5 . The skylight assembly of claim 4 , wherein at least a portion of the torque limiting member detaches when a torque imparted on the second portion reaches or exceeds a predetermined shear strength.

6 . The skylight assembly of claim 4 , wherein the torque limiting member comprises a plurality of blades extending radially from the aperture at a central portion of the torque limiting member.

7 . The skylight assembly of claim 6 , wherein each of the plurality of blades extends from the central portion to a rim portion axially aligned with the second annular wall.

8 . The skylight assembly of claim 7 , wherein each of the plurality of blades meets the rim portion at an outer axial tip, and wherein the outer axial tip comprises a reduced thickness portion having a predetermined shear strength.

9 . The skylight assembly of claim 1 , wherein the first annular wall comprises a first series of threads and the second annular wall comprises a second series of threads rotatable about the first series of threads.

10 . The skylight assembly of claim 1 , wherein an exterior of the second annular wall comprises raised ridges.

11 . The skylight assembly of claim 1 , wherein the first annular wall terminates in a flange.

12 . The skylight assembly of claim 11 , further comprising a gasket coincident with the flange.

13 . A skylight assembly for a vehicle, the skylight assembly comprising:

a first portion comprising a lens and a first annular wall defining a central axis; and

a second portion comprising a second annular wall and a torque limiting member having an aperture coaxial with the central axis;

wherein at least a portion of the torque limiting member detaches when a torque imparted on the second portion reaches or exceeds a predetermined shear strength.

14 . The skylight assembly of claim 13 , wherein the first annular wall comprises at least one securing tab and the second annular wall comprises at least one detent configured to engage with at least a portion of the at least one securing tab.

15 . The skylight assembly of claim 14 , wherein the at least one securing tab comprises a protrusion and the at least one detent comprises a ramped surface and a retention surface for engaging with the protrusion.

16 . The skylight assembly of claim 14 , wherein the at least one securing tab is a plurality of securing tabs coaxial with the central axis and the at least one detent is a plurality of detents coaxial with the central axis.

17 . The skylight assembly of claim 13 , wherein the torque limiting member comprises a plurality of blades extending radially from the aperture at a central portion of the torque limiting member and wherein each of the plurality of blades meets a rim portion of the second portion at an outer axial tip, and wherein the outer axial tip comprises a reduced thickness portion having a predetermined shear strength.

18 . A method of installing a skylight assembly, the method comprising:

providing a panel with an aperture;

inserting a lens portion of the skylight assembly into the aperture, wherein a lens of the lens portion is located on an exterior of the panel and an annular wall of the lens portion is located on an interior of the panel;

rotating a retainer of the skylight assembly onto the annular wall; and

engaging at least one securing tab of the lens portion with at least one detent of the retainer.

19 . The method of claim 18 , further comprising engaging a torque limiting member of the retainer to rotate the retainer.

20 . The method of claim 19 , further comprising detaching a portion of the torque limiting member from the skylight assembly when a torque imparted on the retainer reaches or exceeds a predetermined shear strength.
