Seat for personal watercraft
One example provides a seat assembly for a personal watercraft including a rigid seat support. The rigid seat support includes a base element to be rigidly connected to a deck of the personal watercraft, and a cantilever element rigidly connected to the base element and to extend unsupported above the deck in an aft direction when the base element is connected to the deck.
1. A personal watercraft comprising:
a hull;
a deck disposed on the hull; and
a rigid seat support including:
a base element fixedly attached to the deck; and
a cantilever element fixedly connected to the base element and longitudinally extending unsupported over the deck in an aft direction to form an area free of structure between an underside of the cantilever element and the deck; and
a seat mounted to the rigid seat support, the seat comprising:
a seat pan; and
a seat cushion disposed on an upper side of the seat pan, the seat cushion defining a driver position and a passenger aft of the driver position, wherein at least a portion of the driver position is positioned vertically over the cantilever element.
2. The personal watercraft of claim 1 , the deck including a mounting surface, the base element of the rigid seat support rigidly coupled to the mounting surface.
3. The personal watercraft of claim 2 , the deck defining a rear platform, the mounting surface positioned forward of the rear platform, the cantilever element extending unsupported over the rear platform.
4. The personal watercraft of claim 3 , the cantilever element extending at an upward angle relative to the rear platform.
5. The personal watercraft of claim 3 , the deck defining an elevated superstructure forward of the rear platform, the mounting surface disposed on the superstructure.
6. The personal watercraft of claim 3 , the mounting surface comprising a planar surface parallel to at least one of the rear platform and a waterline of the personal watercraft.
7. The personal watercraft of claim 1 , wherein an entirety of the driver position is positioned vertically over the cantilever element.
8. The personal watercraft of claim 7 , the base element positioned forward of the driver position.
9. The personal watercraft of claim 1 , the rigid seat support having a horizontal length from a forward most connection point to the deck to an aft-most end of the cantilever element in a range from 60 to 85 centimeters.
10. The personal watercraft of claim 9 , the aft-most end of the cantilever element to deflect vertically downward by not more than 3% of the horizontal length.
11. The personal watercraft of claim 1 , the rigid seat support including at least one stiffening member disposed on an underside of the deck opposite the base element, the base element rigidly fixedly attached to the at least one stiffening member with the deck sandwiched there between so as to fixedly attach the base member to the deck and reduce deflection of the deck.
12. The personal watercraft of claim 1 , the base element comprising first and second longitudinally extending base elements, and the cantilever element including first and second longitudinally extending cantilever elements, the first cantilever element rigidly connected to and extending from the first base element and together forming a first longitudinal frame member, and the second cantilever element rigidly connected to and extending from the second base element and together forming a second longitudinal frame member, the first and second longitudinal frame members extending in parallel with one another.
13. The personal watercraft of claim 12 , the deck and hull forming an interior space, the base element of each longitudinal frame member positioned on an outer surface of the deck, the rigid seat support system including an interior support structure disposed within the interior space to which the base element of each frame element is rigidly coupled.
14. The personal watercraft of claim 13 , the deck including a horizontal mounting surface to which the base element of each frame member is rigidly coupled.
15. The personal watercraft of claim 13 , the interior support structure including at least one interior stiffening member disposed along an inner surface of the deck facing the interior space, the base element of each longitudinal frame element coupled to the at least one interior stiffening member with the deck sandwiched there between to prevent deflection of the deck.
16. The personal watercraft of claim 12 , for each longitudinal frame member, the cantilever element extending at an upward angle relative to base element.
17. The personal watercraft of claim 12 , the rigid seat support structure including one or more transverse stiffener elements rigidly connected between the longitudinal frame members to add rigidity to the seat support structure.
18. The personal watercraft of claim 12 , the rigid seat support structure including a stabilizer web rigidly connected between the cantilever elements of the longitudinal member to add rigidity to the seat support structure.
19. A seat assembly for a personal watercraft comprising:
a rigid seat support including:
a base element to be rigidly connected to a deck of the personal watercraft; and
a cantilever element rigidly connected to the base element and to extend unsupported above the deck in an aft direction when the base element is connected to the deck; and
a seat mounted to the rigid seat support, the seat comprising:
a seat pan; and
a seat cushion disposed on an upper side of the seat pan, the seat cushion defining a driver position and a passenger position aft of the driver position, wherein at least a portion of the driver position is positioned vertically over the cantilever element.
