The upright frame members 50c can be positioned at any location and any number of upright frame members 50c may be used. In one embodiment, upright frame members 50 may be positioned in the corners of the upper and lower frame sections. The upright frame members 50c can be secured to the upper and lower frame members 50a, 50b such as by welding. It will be appreciated that the upper frame members 50a, lower frame members 50b and upright frame members 50c can be secured in any other suitable manner. By way of non-limiting example, mechanical fasteners can be used to secure the frame members 50a, 50b and 50c. Similarly, any number of frame members 50a, 50b and 50c may be used. It will be appreciated that the first frame 50 can be made of any suitable material and also may take any suitable configuration.


The first frame 50 may define an open space between the frame members 50a, 50b and 50c. The first frame 50 may include a bracket 52 and may be secured to the deck of a boat using suitable fasteners disposed through the bracket 52 connected to the first frame 50. Similarly, fasteners may extend through the lower frame members 50b and into the boat deck. The first frame 50 may be disposed within the enclosure defined by the seat back retainer portion 12. Also, when the back 14 is in the second position, the frame 50 may be disposed between the sidewalls 44 and at least a portion of back wall 48 of the back 14.


As best seen in FIG. 7, a hinge 54 may be secured to the first frame 50 and to the frame 40 of the back 14 in one embodiment. In this manner, the back 14 is pivotal about the hinge 54 axis between the first and second positions. In one embodiment, a plurality of hinges may be secured to one of the upper frame members 50a.


An actuator generally indicated at 56 may be used to move the back 14 between the first and second positions. The actuator 56 may be positioned in the open space between the frame members 50a, 50b and 50c. In one embodiment, the actuator 56 may be moveably connected to the first frame 50 by a first clevis pin assembly 58. The actuator 56 may alternatively be moveably connected to the bracket 52 by the first clevis pin assembly 58.

The ball screw actuator 64 is driven between an extended position (solid lines in FIG. 4) and a retracted position (dashed lines in FIG. 4). The actuator 56 may pivot during movement between the extended and retracted positions. The electric motor 62 obtains its energy from any suitable source such as a battery or inverter if dock power is used to energize the motor 62 (not shown). In one embodiment, the electric motor may be a reversible DC motor. It will be appreciated, however, that any suitable motor or mechanism may be used as the actuator 56.


The electric motor 62 may be selectively energized via the switch 28. Switch 28 may be a 3-position switch that allows the user to control energization of the actuator 56 and thereby direct the movement of the back 14 between the first and second positions. It will be appreciated that the switch 28 is coupled with the electric motor 62. In one embodiment, the coupling is by way of electrical wires 63. Similarly, the electric motor may be coupled to the electric source by suitable wires (not shown). By using an electric motor 62 and ball screw actuator 64, the back 14 can be selectively positioned in any of an infinite number of positions between the first and second positions. That is, the actuator 56 can be selectively stopped at any location between its extended and retracted positions. The actuator 56 will maintain the back 14 in the desired position when it is not energized. In this manner, the user may select a position that is most comfortable for the user at any time.


The ball screw actuator 64 further includes limit switches (not shown) that limit the stroke of the ball screw actuator 64 to the first and second positions and positions therebetween. That is, if the user attempts to extend the ball screw actuator 64 beyond the extended position, the limit switch will stop energization of the motor 62 and prevent the back 14 from moving past the first position. Similarly, when the ball screw actual 64 is in the retracted position, a limit switch also stops energy to the motor 62 thereby limiting movement of the back 14 to the second position. While one embodiment of an actuator 56 is shown, it will be appreciated that any suitable actuator 56 may be used. Similarly, the actuator 56 can be connected to the back 14 and frame 50, 52 and/or boat deck in any suitable manner.
