Height-adjustable seat for watercraft
View Patent ↗Disclosed adjustable seat systems that provide a self-contained height-adjustable seat system for sit-on-top kayaking that allows the seat to be adjusted into various height and angle positions, while maintaining independent adjustment to the fore/aft position of the seat in the kayak. Some of the adjustable seat systems include a seat upper that includes a seat bottom and a seat back; a seat base adapted to slidably engage a flat surface in the watercraft; and at least two pivot mechanisms coupling the seat upper to the seat base, wherein the at least two pivot mechanisms allow the seat upper to be raised and lowered relative to the seat base. Some of the adjustable seat systems further include a front seat axis, a rear seat axis, a front base axis, and a rear base axis, a front pivot mechanism that pivotally engages both the front seat axis and the front base axis, and a rear pivot mechanism that pivotally engages both the rear seat axis and the rear base axis.

at least two pivot mechanisms coupling the seat upper to the seat base, wherein the at least two pivot mechanisms allow the seat upper to be raised and lowered relative to the seat base,
wherein the seat back is tilt-adjustable, and
wherein an angle of the seat back relative to the seat bottom is adjustable via one or more straps.
2. The seating system of claim 1 , wherein raising the seat upper comprises pivoting the at least two pivot mechanisms in the same direction.
3. An adjustable seating system for a watercraft, comprising:
a seat upper comprising a seat bottom and a seat back;
a seat base adapted to slidably engage a flat surface in the watercraft; and
at least two pivot mechanisms coupling the seat upper to the seat base, wherein the at least two pivot mechanisms allow the seat upper to be raised and lowered relative to the seat base,
wherein the seat back is hingeably coupled to the seat bottom and adapted to fold substantially flat over the seat bottom.
4. The adjustable seating system of claim 3 , wherein the adjustable seating system is configured to removably couple to the watercraft via one or more front adjustment straps and one or more rear tensioning members.
5. The seating system of claim 3 , wherein raising the seat upper comprises pivoting the at least two pivot mechanisms in the same direction.
6. An adjustable seating system for a watercraft, comprising:
a seat upper comprising a seat bottom and a seat back;
a seat base; and
at least two pivot mechanisms coupling the seat upper to the seat base,
wherein the at least two pivot mechanisms allow the seat upper to be raised and lowered relative to the seat base,
wherein the seat upper comprises a front seat axis and a rear seat axis fixed relative to the seat upper,
wherein the seat base comprises a front base axis and a rear base axis fixed relative to the seat base, and
wherein the at least two pivot mechanisms comprise a front pivot mechanism that pivotally engages both the front seat axis and the front base axis, and a rear pivot mechanism that pivotally engages both the rear seat axis and the rear base axis,
wherein the seat bottom remains substantially horizontal as the seat upper is raised and lowered relative to the seat base.
7. The seating system of claim 6 ,
wherein the seat base is adapted to slidably engage the watercraft.
8. The seating system of claim 6 ,
wherein an angle of the seat back relative to the seat bottom is adjustable.
9. The seating system of claim 6 ,
wherein the front pivot mechanism and the rear pivot mechanism are able to pivot independent from one another to position the seat upper in a reclined position.
10. The seating system of claim 6 , wherein raising the seat upper comprises pivoting the at least two pivot mechanisms in the same direction.
11. An adjustable seating system for a watercraft, comprising:
a seat upper comprising a seat bottom and a seat back;
a seat base; and
at least two pivot mechanisms coupling the seat upper to the seat base,
wherein the at least two pivot mechanisms allow the seat upper to be raised and lowered relative to the seat base,
wherein the at least two pivot mechanisms comprise a front pivot mechanism, and a rear pivot mechanism,
wherein each pivot mechanism has a first position and a second position, where the first position is raised relative to the second position,
wherein when the front and rear pivot mechanisms are each in the first position the seat bottom is substantially parallel with the seat base and the front pivot mechanism is parallel with the rear pivot mechanism;
wherein when the front and rear pivot mechanisms are each in the second position, the seat bottom is substantially parallel with the seat base and the front pivot mechanism is parallel with the rear pivot mechanism.
12. The seating system of claim 11 ,
wherein the seat base is adapted to slidably engage the watercraft.
13. The seating system of claim 11 ,
wherein an angle of the seat back relative to the seat bottom is adjustable.
14. The seating system of claim 11 ,
wherein the front pivot mechanism and the rear pivot mechanism are able to pivot independent from one another to position the seat upper in a reclined position.
15. The seating system of claim 11 , wherein raising the seat upper comprises pivoting the at least two pivot mechanisms in the same direction.
16. An adjustable seating system for a watercraft, comprising:
a seat upper;
a seat base; and
at least a front pivot mechanism and a rear pivot mechanism coupling the seat upper to the seat base to allow the seat upper to travel between a first position and a second position with respect to the seat base, where the first position is raised relative to the second position,
wherein the seat upper in the first position is in a first location along a fore/aft direction of the watercraft, the seat upper in the second position is in a second location along a fore/aft direction of the watercraft, and the first location and the second location are different,
wherein the front pivot mechanism is substantially parallel with the rear pivot mechanism in the first position, and the front pivot mechanism is substantially parallel with the rear pivot mechanism in the second position.
17. The seating system of claim 16 ,
wherein the seat base is adapted to slidably engage the watercraft.
18. The seating system of claim 16 ,
wherein the seat upper comprises a seat bottom and a seat back, and
wherein an angle of the seat back relative to the seat bottom is adjustable.
19. The seating system of claim 16 ,
wherein the front pivot mechanism and the rear pivot mechanism are able to pivot independent from one another to position the seat upper in a reclined position.
