Abstract
The present invention includes a boat having a seat with a pneumatically adjustable passenger ride-height, for a given passenger and/or an adjustable passenger weight range for a given ride height range and with an adjustable rebound damping mechanism, where adding air results in a lifting of the seat, and rotating a member results in change of the rebound speed.
Claims16
A seating system for supporting a person in an adjustable elevated position above a lower portion of a boat, where the seating system comprises:
- a boat seat having a bottom portion;
- a boat seat base portion configured to couple with said bottom portion of said boat seat;
- a base member portion configured to couple with a portion of a boat, which is generally lower than a predetermined boat seat height;
- an adjustable length pedestal disposed between said boat seat base portion and said base member portion, said adjustable length pedestal comprising:
- a first tube;
- a second tube;
- said second tube at least partially nested within said first tube;
- an air chamber disposed wholly within one of said first tube and said second tube;
- an oil chamber disposed wholly within another of said first tube and said second tube;
- said oil chamber being variably disposed within said one of said first tube and said second tube;
- a piston disposed wholly within said oil chamber and coupled to a portion of said one of said first tube and said second tube;
- means for introducing pressurized air into said air chamber where an increase in air pressure in said air chamber results in an adjustment of support provided for said boat seat, and
- means for adjustably restricting an oil flow rate from one side of said piston to another side of said piston and thereby adjustably limiting a rebound rate of said piston after a temporary force applied to said boat seat pedestal is reduced.

- a boat seat having a bottom portion;
- a boat seat base portion configured to couple with said bottom portion of said boat seat;
- a base member portion configured to couple with a portion of a boat, which is generally lower than a predetermined boat seat height;
- an adjustable length pedestal disposed between said boat seat base portion and said base member portion, said adjustable length pedestal comprising:
- a first tube;
- a second tube;
- said second tube at least partially nested within said first tube;
- an air chamber disposed wholly within said first tube;
- an oil chamber disposed wholly within said second tube;
- said oil chamber also being variably disposed within said first tube;
- a piston disposed wholly within said oil chamber and coupled to a portion of said one of said first tube;
- means for introducing pressurized air into said air chamber where an increase in air pressure in said air chamber results in an increase in one of:
- ride-height of said boat seat for a given passenger or an increase in passenger weight for a given ride height;
- wherein said piston is coupled by a shaft through said air chamber with said first tube;
- wherein said shaft is a hollow shaft;
- and
- means for adjustably restricting an oil flow rate from one side of said piston to another side of said piston and thereby adjustably limiting a rebound rate of said piston after a temporary force applied to said boat seat pedestal is reduced.

- means for adjusting a ride-height of said boat seat, until a maximum seat height is reached;
- and
- means for adjustably limiting a rebound rate of said piston after a temporary force applied to said boat seat pedestal is reduced.
