CLAIMS:
1. A lumbar support device for a specific user seated on a specific seat, the lumbar support device including:
a substantially rigid body defining a peripheral region, a rear surface having geometry defined by geometry of the specific seat, and an opposed front surface having geometry defined by a lumbar region of the specific user; and
a resiliently deformable layer covering at least a portion of the front surface.
2 The lumbar support device of claim 1 also including a cover arranged to cover the resiliently deformable layer and at least a portion of the body.
3. The lumbar support device of claim 1 or 2, wherein the rear surface is defined by a rim extending at least partially around the peripheral region.
4. The lumbar support device of claim 3, wherein the rim discontinuously extends around the peripheral region to form a plurality of feet.
8 The lumbar support device of any preceding claim, wherein the resiliently deformable layer is shaped such that its thickness tapers towards the peripheral region.
6. The lumbar support device of claim 5, wherein the body defines an operatively top end, bottom end and opposed sides, and wherein the taper of the resiliently deformable layer towards the bottom end defines a steeper gradient than a gradient of the taper towards the top end.
7. The lumbar support device of claim 6, wherein the taper of the resiliently deformable layer towards each of the sides defines an equal gradient.
8. The lumbar support device of claim 7, wherein the taper of the resiliently deformable layer towards each of the sides defines a gradient which is equal to or greater than the gradient of the taper towards the bottom end.
9. The lumbar support device of any preceding claim, wherein the body is a unitary body which defines the rear surface and the front surface.
10. The lumbar support device of any preceding claim, also including a belt secured to the body, the belt defining two ends and at least one end is associated with a fastening mechanism operable to releasably fasten the ends together to secure the device to the user.
11. A method for producing a lumbar support device for a specific user seated on a specific seat, the method including:
obtaining three-dimensional (3D) geometry data from geometry defined by the specific seat;
obtaining 3D geometry data from geometry defined by a lumbar region of the specific user;
fabricating a substantially rigid body to define a peripheral region, a rear surface having geometry defined by the 3D geometry data relating to the specific seat, and an opposed front surface having geometry defined by the 3D geometry data relating to the specific user; and
mounting a resiliently deformable layer to the body to cover at least a portion of the front surface.
12. The method of claim 11, wherein obtaining the 3D geometry data relating to the specific user includes operating a 3D scanner to scan the lumbar region of the user.
13. The method of claim 12, wherein scanning the lumbar region of the user includes scanning the lumbar region arranged in each of a plurality of positions relative to the specific seat, and wherein obtaining the 3D geometry data relating to the specific user includes averaging the 3D geometry data obtained from the plurality of scans.
14. The method of any of claims 11 to 13, wherein obtaining the 3D geometry data relating to the specific seat includes operating a 3D scanner to scan the seat.
15. The method of any of claims 11 to 14, also including shaping the resiliently deformable layer such that its thickness tapers towards the peripheral region.
16. The method of claim 15, wherein the body defines an operatively top end, bottom end and opposed sides, and shaping the resiliently deformable layer to taper towards the peripheral region includes shaping the taper towards the bottom end to define a steeper gradient than a gradient of the taper towards the top end.
17. The method of claim 16, wherein shaping the resiliently deformable layer to taper towards the peripheral region includes shaping the taper towards each side to define a gradient which is equal to or greater than the gradient of the taper towards the bottom end.
