BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to boat seats and lounges, and more particularly, to boat seats and lounges for use in performance and pleasure boats, and such boats and lounges having a stowable seat back.
2. Description of the Prior Art
A typical sun lounge and/or seat in a boat requires substantial movement of a seat cushion or support structure in order to switch between a seating configuration and a sunpad configuration which provides a flat surface on which to lay for sunbathing. The substantial movement is required, in part because the seat cushion or support structure must first be vertically lifted and then, in some cases, movement of the seat surface must occur to extend the seat surface into a larger horizontal surface flattening out what would normally have been the seat back. This is undesirable in many cases because it takes up greater amounts of space within the boat cockpit, space which may be required for quick movement within the boat cockpit.
One example of a seat with an adjustable seat back is disclosed in U.S. Patent Publication 2007/0158986 in which an adjustable sun lounge converts from a seating configuration into a sunbathing configuration. A backrest can be in a substantially horizontal position after moving from an upright position via a single pivot hinge. It should be noted that for purposes of this disclosure, the terms “seat” and “lounge” are used interchangeably and generally refer to such seats or lounges which include a backrest.
Another example of convertible prior art seats and lounges is disclosed in U.S. Pat. No. 9,021,975 which describes a seating system for marine vessels including a chair having a backrest and a seat bottom. The seating system is convertible between a forward-facing seat configuration and an aft-facing lounge configuration. In the aft-facing lounge configuration an extension element and seat bottom are substantially parallel to one another. In the forward-facing configuration, the extension element is substantially upright and at an acute angle with respect to the seat bottom. As discussed with other prior art configurations, to remove or eliminate the seat back requires an extension of the seat in length taking up further space within the boat cockpit.
The problem of having a seat back that can be removed within the environment of a boat without requiring extension of the seat with which it is associated, is overcome in accordance with the seat and system of the invention as further described herein.
BRIEF SUMMARY OF THE INVENTION
In one aspect, there is provided a seat, having a seating surface support and a seating surface, for a boat cockpit. The seat has a stowable seat back. The seat is constructed to be mounted in contact with, secured to, or adjacent an inner wall of the hull of a boat. A seat back is mounted on the seat, typically through a pivoting mechanism, to be selectively deployed and stowed.
When deployed the seat back extends, typically substantially perpendicular to the inner wall of the hull of a boat with which the seat is in contact or adjacent for providing a support for a user's back. A vertically extending rod which comprises a rotatable pivot arm is mounted on the seat support at a location proximate the inner wall of the boat hull, and also secured within the seat back at a location proximate the inner wall for supporting the seat back. The vertically extending rod is rotatable about its axis to allow the seat back to be rotated between a deployed position, and a stowed position wherein the seat back is flush against the inner wall of the boat hull. A second rod which comprises a locking arm extends downwardly from the seat back to be locked to the seat support at a female locking member when the seat back is deployed for supporting the seat back in its deployed position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Having generally described the invention and the figures, the invention will become more clearly evident from the following detailed discussion of embodiments thereof presented herein.
A boat seat 13 with a stowable seat back 15 is generally illustrated in FIGS. 1 and 2 as assembled within the cockpit of a boat 11. In FIG. 1 a stowable seat back 15 is shown deployed for use, and in FIG. 2 the stowable seat back 15 is shown in stowed position to make up part of a bolster system 17. The seat 13 is an assembly of elements as described herein, and includes a seating surface 19 on a seating surface support (not numbered).
FIG. 3 illustrates in greater detail the seat 13 and stowable seat back 15 shown with the seating surface 19 removed to reveal a storage compartment 21 underneath where the seating surface 19 is normally located. In this embodiment the stowage compartment 21 makes up the seating surface support. The stowable seat back 15 is supported at a location proximate and in abutment with the inner wall of the hull of the boat 11 through a pivot arm 23, which is rotatable about its axis. There is also shown a locking arm 25 with a male locking projection 27 which, when the seat back 15 is rotated into a deployed position, engages with female locking member 29 mounted on the seating surface support, e.g., stowage compartment 21 for locking the seat back 15 in a deployed position.
FIG. 3 also illustrates a recessed cutout 39 on a portion of the inner wall of the hull for receiving locking arm 25 allowing the seat back 15 to be stowed flush against the inner wall to form part of bolster system 17.
FIG. 4 illustrates in greater detail the locking mechanism in which the locking arm 25 can be moved to have the male locking projection 27 pass into a receiving aperture of female locking member 29 to deploy the seat back 15.
FIG. 5 illustrates in perspective view the stowable seat back 15 being moved from a stowed position into a deployed position.
FIG. 6 shows the seat back 15 moved completely into a deployed position with the locking arm 25 engaged with the female locking member 29 through entry of the male locking projection 27 into a recess in the female locking member 29.
FIG. 7 is a view from the back of the seat back 15, with the seat back 15 in a deployed position, and further illustrating a male stow-lock member 31 on the inner wall of the hull which is received within female stow-lock member 33 on the back of the seat back 15 when the seat back 15 is stowed. More specifically, the two members 31 and 33 lock with each other to prevent the seat back 15 from swinging freely away from the inner wall of the hull.
FIG. 8 illustrates a paddle latch 35 which is connected to an internal mechanism within the seat back 15, which allows the seat back 15 to be moved between an elevated position and a lowered position. As will be appreciated, the internal mechanism is conventional and allows the seat back 15 to slide up and down pivot arm 23 and locking arm 25.
FIG. 9 illustrates how the paddle latch 35 is engaged by a user to raise the seat back 15.
FIG. 10 illustrates how the paddle latch 35 can be used to move the seat back 15 into a lower position.
FIG. 11 is an enlarged view showing the locking arm 25 engaged with the female locking member 29. The female locking member 29 includes a spring loaded slide catch 37 which, when the male locking projection 27 of the locking arm 25 is received within the aperture of the female locking member 29, serves to engage the male locking projection 27 in a locked manner.
FIG. 12 is a perspective view from the front of the seat assembly and shows the seat back 15 in a deployed position shown without the seating surface 19 on the seating surface support, e.g. stowage compartment 21, and showing the storage compartment 21, which is below the seating surface 19.
FIG. 13 is an enlarged view of the male stow-lock member 31, which is secured to the inner wall of the hull for locking the seat back 15 in a stowed position. The enlarged portion of the male stow-lock member 31 is typically made of an elastomeric material such as rubber, which can be press-fit into the female stow-lock member 33 which is attached to the back of the seat back 15 as more clearly shown in FIG. 14.
FIG. 15 illustrates in an enlarged view the female locking member 29 with a spring loaded slide catch 37 to engage the male locking projection 27 on the locking arm 25.
FIG. 16 is an enlarged view of the locking arm 25 and female locking member 29 with a spring loaded slide catch 37. The male locking projection 27 is shown enlarged in this figure, and includes a slot region which is engaged with the spring loaded slide catch 37 when the male locking projection 27 is received within the aperture of the female locking member 29.
FIG. 17 illustrates in a disassembled view the male stow-lock member 31 which includes the enlarged elastomeric portion 41, which is received within the female stow-lock member 33, and includes a connection member 43 which when assembled allows the male stow-lock member 31, to be secured to the inner wall of the hull of a boat 11.
While this invention has been described as having exemplary designs, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principals. Further, this application is intended to cover such departures from the present disclosure as come within the known and customary practice in the art to which this invention pertains.
