Abstract

A sofa base system includes a plurality of channel assemblies and a motor. The channel assemblies are disposed on a frame portion adapted for operational engagement with an associated vehicle, and each channel assembly includes a sliding bracket and an outer bracket arranged on the sliding bracket, as well as a guide rod. The sliding bracket and outer bracket are arranged to slide on the guide rods via a plurality of roller members. The sliding bracket and an outer bracket are coupled to a shuttle member that is drive by a drive rod, and the drive rod is operatively connected to the motor via drive shafts and gearboxes.

First claim

What is claimed is:

1. A sofa base comprising:
a first and a second channel assembly that each include a channel member and a guide rod extending along a length of the channel member, wherein the first channel assembly further includes a drive member extending within the channel member parallel to the guide rod; and
a first and a second slide assembly respectively coupled to the first and a second channel assembly, the first and the second slide assembly each configured to translate along the length of the channel member and each having a plurality of rollers that engage the guide rod, wherein the first slide assembly further includes a driven member arranged on the drive member and configured to translate axially along the drive member upon rotation of the drive member,
wherein the channel member of the first channel assembly includes a pair of slots extending parallel with the drive member, and the driven member includes at least one guide member that is configured to extend into the pair of slots.

2. The sofa base of claim 1 , wherein the drive member is a threaded rod configured to rotate within the channel member and the driven member includes a drive nut that is coupled to the first slide assembly.

3. The sofa base of claim 1 , wherein each of the pair of slots expands into a rear opening at a rear end of the slot and a front opening at a front end of the slot.

4. The sofa base of claim 3 , the rear opening includes a lip at a front wall of the rear opening, wherein the lip is configured to catch the at least one guide member.

5. The sofa base of claim 3 , wherein each of the slots includes a central portion extending between the rear opening and the front opening, the central portion being narrower than the front and rear openings.

6. The sofa base of claim 1 , wherein each of the slide assemblies includes a first bracket and at least some of the plurality of rollers are arranged within the first bracket.

7. The sofa base of claim 6 , wherein the plurality of rollers arranged within the first bracket are oriented normal to the guide rod.

8. The sofa base of claim 6 , wherein each of the slide assemblies further includes a second bracket and at least some of the plurality of rollers are arranged within the second bracket.

9. The sofa base of claim 8 , wherein the plurality of rollers arranged within the second bracket are oriented normal to both the guide rod and the rollers arranged within the first bracket.

10. The sofa base of claim 8 , wherein the first bracket includes at least one support rod extending upward therefrom normal to the guide rod, and wherein the second bracket includes at least one opening that receives the at least one support rod of the first bracket when the first bracket is nested within the second bracket.

11. The sofa base of claim 10 , wherein the second bracket includes a support rod extending upward therefrom parallel with at least one support rod of the first bracket.

12. The sofa base of claim 11 , wherein a seat assembly is installed to the support rods of the first and second brackets.

13. The sofa base of claim 8 , wherein the channel member of the first channel assembly includes a pair of slots extending parallel with the drive member, and the driven member includes at least one guide member that is configured to extend into the pair of slots, and the at least one guide member is attached to the second bracket such that the slide assembly translates with the driven member.

14. The sofa base of claim 8 , wherein a gusset is provided on the channel member of at least the first channel assembly, wherein the gusset is configured to inhibit rearward translation of the slide assembly from a forward position to a rearward position when an upward force is applied to a front portion of the slide assembly.

15. The sofa base of claim 1 , further comprising a motor configured to cause rotation of the drive member.

16. The sofa base of claim 15 , wherein the motor rotates a drive shaft and the drive member is coupled to a gear box that redirects rotation of the drive shaft.

17. The sofa base of claim 1 , wherein the second channel assembly further includes a second drive member extending within the channel member parallel to the guide rod, and wherein the second slide assembly further includes a second driven member arranged on the second drive member and configured to translate axially along the second drive member upon rotation of the second drive member.

18. The sofa base of claim 1 , further comprising at least a third channel assembly and a third slide assembly that is coupled to the third channel assembly and configured to translate along a length of the third channel assembly.

19. The sofa base of claim 1 , wherein first and second channel assemblies are provided on a frame.

20. The sofa base of claim 1 , wherein the drive member is constrained by the first channel assembly.

21. The sofa base of claim 1 , wherein the driven member is constrained by the first slide assembly.

22. A sofa base comprising:
a first and a second channel assembly that each include a channel member and a guide rod extending along a length of the channel member, wherein the first channel assembly further includes a drive member extending within the channel member parallel to the guide rod; and
a first and a second slide assembly respectively coupled to the first and a second channel assembly, the first and the second slide assembly each configured to translate along the length of the channel member and each having a plurality of rollers that engage the guide rod, wherein the first slide assembly further includes a driven member arranged on the drive member and configured to translate axially along the drive member upon rotation of the drive member,
wherein the guide rod is arranged external of the channel member associated therewith.

23. A sofa base comprising:
a first and a second channel assembly that each include a channel member and a guide rod extending along a length of the channel member, wherein the first channel assembly further includes a drive member extending within the channel member parallel to the guide rod; and
a first and a second slide assembly respectively coupled to the first and a second channel assembly, the first and the second slide assembly each configured to translate along the length of the channel member and each having a plurality of rollers that engage the guide rod, wherein the first slide assembly further includes a driven member arranged on the drive member and configured to translate axially along the drive member upon rotation of the drive member,
wherein each of the slide assemblies includes a first bracket and a second bracket wherein the first bracket includes at least one support rod extending upward therefrom normal to the guide rod, and wherein the second bracket includes at least one opening that receives the at least one support rod of the first bracket when the first bracket is nested within the second bracket.
