Motorcycle seat assembly with hammock-type suspension
A motorcycle seat assembly that includes a seat pan with a load bearing hammock-type or hammock-style fabric or mesh seat suspension mounted using a suspension mounting bracket to the seat pan that is configured with an integral suspension mounting fixture that enables pre-tensioning of a stretchable webbing of load-bearing fabric or mesh material of the suspension during fixturing and/or mounting of the suspension to the seat pan.
1. A motorcycle seat assembly comprising:
a seat pan;
a bracket mounted to the seat pan;
a seat suspension assembly including first and second mounts and a webbing of load-supporting fabric or mesh extending between the first and second mounts, wherein the webbing is spaced above a portion of the seat pan underlying the seat suspension assembly;
a seat suspension assembly fixture provided at least in part by the bracket and including first and second spaced apart retainers configured to engage the first and second mounts of the seat suspension assembly with the first mount engaging the first retainer and the second mount slidably guided by the second retainer so that the seat suspension assembly is in a fixtured configuration in which the webbing has less than a threshold operating tension; and
a fastener configured to transition the seat suspension assembly from the fixtured configuration to a mounted configuration in which the fastener secures the second mount of the seat suspension assembly with respect to the seat pan and the bracket, wherein the second mount of the seat suspension assembly is in a position spaced from the second retainer in the mounted configuration so that the webbing is held with at least the threshold operating tension.
2. The motorcycle seat assembly of claim 1 , wherein the first retainer and the second retainer are provided by the bracket and the first retainer provides a first bracket mount to which the first mount of the seat suspension assembly is immovably secured.
3. The motorcycle seat assembly of claim 1 , wherein the fastener is engaged with a mount of the bracket to secure the second mount of the seat suspension assembly thereto.
4. The motorcycle seat assembly of claim 3 , further comprising an additional fastener securing the second mount of the seat suspension assembly to the seat pan alongside the bracket.
5. The motorcycle seat assembly of claim 1 , wherein the first retainer is formed by a mounting tongue of the bracket and the second retainer is formed by a retainer tab of the bracket.
6. The motorcycle seat assembly of claim 5 , wherein the retainer tab forming the second retainer at least partially defines a mounting pocket for receiving the second mount of the seat suspension assembly.
7. The motorcycle seat assembly of claim 5 , wherein the second retainer is aft of the first retainer.
8. The motorcycle seat assembly of claim 1 , wherein the second mount of the seat suspension assembly comprises an elongate transversely-extending suspension mounting beam that is anchored to the bracket by the fastener and anchored to the seat pan on opposing sides of the bracket by two additional fasteners.
9. The motorcycle seat assembly of claim 1 , wherein the bracket is elongate and extends centrally longitudinally along a seat saddle portion of the seat pan that underlies a driver or operator sitting in the motorcycle seat assembly, the bracket providing a backbone to the seat pan that reinforces the seat pan.
10. The motorcycle seat assembly of claim 1 , wherein the seat base assembly further comprises a plurality of pairs of vibration isolators disposed on a bottom side of the seat pan and adapted to face a chassis or frame of a motorcycle to which the motorcycle seat assembly is mounted.
11. The motorcycle seat assembly of claim 1 , wherein the bracket has a length greater than one-half of the length of the seat pan.
12. The motorcycle seat assembly of claim 1 , wherein the bracket has a width greater than one-half of the width of the seat pan at the point of narrowest width of the seat pan.
13. The motorcycle seat assembly of claim 1 , wherein the bracket has a length greater than one-half of the length of the seat pan and the bracket has a width greater than one-half of the width of the seat pan at the point of narrowest portion or section of the seat pan.
14. The motorcycle seat assembly of claim 1 , wherein the webbing is comprised of an elastomeric mesh or fabric.
15. The motorcycle seat assembly of claim 14 , wherein the elastomeric mesh or fabric of the webbing is comprised of woven polyester, a copolymer elastomer, a copolymer thermoplastic elastomer, a copolyester elastomer, or a copolyester thermoplastic elastomer.
16. The motorcycle seat assembly of claim 1 , wherein the webbing is under a first non-zero amount of pretension when the seat suspension assembly is in the fixtured configuration.
17. The motorcycle seat assembly of claim 1 , wherein the bracket comprises a backrest mounting support for mounting a backrest thereto.
18. The motorcycle seat assembly of claim 17 , further comprising a removable and position-adjustable backrest mounted to the backrest mounting support of the bracket.
19. The motorcycle seat assembly of claim 18 , wherein the removable and position-adjustable backrest is height adjustable and angle adjustable.
