DETAILED DESCRIPTION

In the present description, certain terms have been used for brevity, clarity, and understanding. No unnecessary limitations are to be inferred therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes only and are intended to be broadly construed.

FIGS. 1-3 illustrate a convertible seating system 100 for a marine vessel in accordance with an exemplary preferred embodiment of the present disclosure. Specifically, FIG. 1 depicts a perspective view of the convertible seating system 100 in a stowed configuration, FIG. 2 depicts an exploded view of the system 100, and FIG. 3 depicts a side cross-sectional view of the system 100 in the stowed configuration. Existing convertible seating systems for marine vessels often include folding backrests that are pivoted downwardly to provide a flat casting sterndeck surface and pivoted upwardly to reveal a seating surface that is recessed below the sterndeck surface. Although simple to implement, the present inventor has recognized that recessed seating surfaces have poor ergonomics and are uncomfortable. Therefore, the convertible seating system of the present disclosure includes a seating base that pivots upwardly as a backrest is pivoted upwardly from a stowed position. In this way, the seating base is raised to a position that is flush or level with the sterndeck surface, rather than recessed, resulting in more favorable ergonomics and a more comfortable seat. Advantageously, as described below, the mechanics of the convertible seating system disclosed herein cause the seating base to be “ratcheted” or automatically raised as the backrest is pivoted, bringing the seating system into a deployed position through a single action performed by the user in raising the backrest.

The convertible seating system 100 is shown to be generally comprised of a backrest component 102 and a ratcheting seat component 104. While in the stowed configuration, a top surface of the backrest component 102 is flush with the deck surface 106, and the seat component 104 resides within a recessed compartment or cavity 108 that is formed in the deck surface 106. In an exemplary implementation, sidewall stop components 132 and back wall ledge components 136 are respectively coupled to the sidewalls 134 and the back wall 138 of the cavity 108, and backrest stop component 140 is positioned within the cavity 108.

The backrest component 102 is shown to be pivotably coupled to a deck component 110 using a pair of aft heavy duty hinges 112. The style of hinges 112 is not particularly limited. By pivotably coupling the backrest component 102 to the deck component 110, the backrest component 102 can be rotated between the stowed position (depicted in FIGS. 1 and 3), and a deployed position (depicted in FIG. 6). A bottom surface of the deck component 110 rests atop the sidewall stop components 132 and the back wall ledge components 136 such that a top surface of the deck component 110 is flush with the deck surface 106. While in the stowed position, a bottom surface of the backrest component 102 likewise rests on the sidewall stop components 132 such that a top surface of the backrest component 102 is flush with the deck surface 106 and the deck component 110, and the backrest component 102 is prevented from pivoting downwardly into the cavity 108.

The convertible seating system 100 is further shown to include a backrest cushion 114 and a seat cushion 116 that increase the comfort and aesthetic qualities of the seating system 100. In an exemplary implementation, the backrest cushion 114 and the seat cushion 116 are fixedly coupled to the backrest component 102 and the seat component 104, respectively. In other implementations, the backrest cushion 114 and the seat cushion 116 are detachably coupled to the backrest component 102 and the seat component 104 using any suitable detachable fastening mechanism (e.g., snaps, magnets, laces or ties).

Specifically referring to FIGS. 2 and 3, the backrest component 102 is shown to include a backrest cushion support portion 118 and a backrest projecting portion 120 that is generally orthogonal to the support portion 118. In various implementations, the support portion 118 and the projecting portion 120 may be fabricated as a single part, or as multiple parts that are assembled to each other. The seat component 104 is shown to include a seat cushion support portion 122, a seat projecting portion 124, and a seat locking projecting portion 126 (see FIG. 3) that is generally orthogonal to the seat cushion support portion 122 and the seat projecting portion 124. In various implementations, the support portion 122, projecting portion 124, and locking portion 126 may be fabricated as a single part, or as multiple parts that are assembled to each other. The seat projecting portion 124 is shown to be pivotably coupled to the recessed deck compartment 108 using a pair of fore heavy duty hinges 128. In an exemplary implementation, the aft hinges 128 are identical to the fore hinges 112.

FIGS. 4 and 5 depict the convertible seating system 100 in partially deployed or intermediate configurations as the backrest component 102 is pivoted from the stowed configuration to the deployed configuration. In some implementations, a handle may be provided on the backrest component 102 to assist a user in grasping and pivoting the backrest component 102. As specifically depicted in FIG. 4, as a user pivots the backrest component 102 upwardly, the projecting portion 120 of the backrest component 102 is brought into contact with the locking portion 126 of the seat component 104. As shown in FIG. 5, as the backrest component continues to pivot upwardly, engagement between the locking portion 126 and the projecting portion 120 causes the seat component 104 to likewise pivot upwardly via the hinges 128. The pivoting movement of the seat component 104 causes the locking portion 126 to slide rearwardly relative to the projecting portion 120 until the locking portion 126 rests within a recess 130 that is formed between the backrest cushion support portion 118 and the projecting portion 120 of the backrest component 102 (see FIG. 6).

FIG. 6 depicts the convertible seating system 100 in the fully deployed configuration. As described above, in the fully deployed configuration, the ratcheting seat component 104, the deck surface 106, and the deck component 110 are flush or level with each other, resulting in an ergonomically favorable and comfortable seat. Over-rotation or over-reclining of the backrest component 102 in the fully deployed position may be prevented via contact between a lower portion 142 of the backrest support portion 118 and the backrest stop component 140. In some implementations, the projecting portion 120 may include one or more chamfered edges to ensure adequate clearance between the projecting portion 120 as the backrest component 102 rotates between the stowed and deployed configurations.

In some implementations, as depicted in FIGS. 7 and 8, the seat component 104 includes at least one locking pin assembly 144 to help retain the convertible seating system 100 in the fully deployed configuration. For example, the seating system 100 may include a pair of pin assemblies 144. Each pin assembly 144 is shown to include a pin retention block 146 that is coupled to the support portion 122 of the seat component 104 and located opposite the seat cushion 116. A retention pin 148 and a spring 150 are shown to be positioned within each pin retention block 146. The springs 150 are configured to bias the retention pins 148 into recesses 152 formed in the sidewall stop components 132. Seating the pins 148 into the recesses 152 arrests movement of the seat component 104 relative to the cavity 108. To rotate the seat component 104 downwardly into the stowed position within the cavity 108, a user pulls the pins 148 inwardly as indicated by arrows 154, compressing the springs 150 and drawing the pins 148 out of the recesses 152.

In the present disclosure, certain terms have been used for brevity, clarity, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes only and are intended to be broadly construed. The different systems and methods described herein may be used alone or in combination with other systems and devices. Various equivalents, alternatives and modifications are possible within the scope of the appended claims.
