The present specification generally relates to vehicle seat assemblies and, more specifically, a vehicle seat assembly having a bracket allowing for a more compact storage when the seat is stowed.
Vehicle seat assemblies which have reclining capability are known in the art. Current vehicle seats exist with a capability of stowing into a compartment within a vehicle. The vehicle seat commonly folds onto itself to a compact position to be stowed within a compartment. However, when the vehicle seat is folded onto itself, the seat is still large thus requiring a large compartment within the vehicle floor.
Furthermore, it is known to provide a seat assembly which folds up to more easily stow the vehicle seat. However, when the seat assemblies of the prior art are stowed, they take up a substantial amount of room within the storage areas of the vehicle.
Accordingly, a need exists for alternative vehicle seat assemblies providing for improved packaging and stowability.
In one embodiment, a vehicle seat assembly includes a seat bottom and a seat back, the seat back pivotally connected to the seat bottom by a bracket, the bracket having a seat bottom portion and a seat back portion, the seat bottom portion arranged at an angle θ with respect to the seat back portion, the seat bottom portion providing a main pivot axis extending through the seat bottom and a distal end of the seat back portion of the bracket connected to the seat back so as to pivot the seat back with respect to the seat bottom along the main pivot axis, the seat back configured to rotate to a position on top of the seat bottom to a forward and stowed position.
In other embodiments, bracket for a vehicle seat is provided where the bracket is used to connect a seat bottom to a seat back, the seat bottom having a main pivot axis extending therethrough. The bracket may include a seat bottom portion and a seat back portion, the seat bottom the seat bottom portion arranged at an angle θ with respect to the seat back portion and a distal end of the seat bottom portion of the bracket pivotally connected to the main pivot axis, the distal end of the seat back portion of the bracket connected to the seat back so as to pivot the seat back with respect to the seat bottom, the seat back configured to rotate to a position on top of the seat bottom to a forward and stowed position.
In yet another embodiment, a vehicle is provided having a floor having a bucket and a seat having a seat bottom and a seat back, the seat back pivotally connected to the seat bottom by a bracket, the bracket having a seat bottom portion and a seat back portion, the seat bottom portion arranged at an angle θ with respect to the seat back portion, a main pivot axis extending through the seat bottom, the main pivot spaced apart from an edge of the seat bottom, a distal end of the seat bottom portion of the bracket pivotally connected to the main pivot axis, the distal end of the seat back portion of the bracket connected to the seat back so as to pivot the seat back with respect to the seat bottom, the seat back configured to rotate to a position on top of the seat bottom to a forward and stowed position wherein the seat is configured to move from a use position to a stowed position, the stowed position where the seat back is rotated over and onto the seat bottom, the stowed position further defined when the seat is positioned within the bucket.
These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.

As described above, the bracket 106 has two distal ends 114, 116 spaced apart from the bend 115. In the some embodiments, the distal ends 114, 116 are rounded but may alternatively be squared off or any other suitable shape. In the present embodiment, the bend 115 includes an outer edge which is also curved or rounded to proceed an aesthetically appealing appearance. Alternatively, the bend 115 may be square or any other suitable shape.
The distal end 116 of the seat back portion 108 of the bracket 106 connects directly to the seat back 102. The seat back 102 includes a proximal end 124 and a distal end 126. The distal end 116 of the seat back portion 108 of the bracket 106 connects directly to the proximal end 124 of the seat back 102. The distal end 126 of the seat back 102 may further include a head rest 128 having a pivot axis 130. In some embodiments, the head rest 128 is pivotable about the pivot axis 130 to provide for a more compact packaging during a stowed position.
The seat bottom 104 includes a proximal end 120 and a distal end 122. The distal end 114 of the seat bottom portion 110 of the bracket 106 connects to the proximal end 120 of the seat bottom 104. The main pivot axis 112 extends generally horizontally through the seat bottom 104, such as illustrated by reference D of
The main pivot axis 112 is located forward of the seat back portion 104. In particular, the main pivot axis 112 is offset forward or toward the distal end 122 of the seat bottom 104 away from a geometric center of the seat back portion 108 of the bracket 106. The amount of offset of the pivot axis 112 from the seat back portion 108 (and the seat back 102) can correspond to space savings when the seat assembly 100 is placed ion the stowed position, as will be described below. The seat back 102 and the seat bottom 104 are unhinged at their interface which allows for forward movement of the seat back 102 relative to the seat bottom 104.
Referring to
During movement from the use position A to the stowed position B, the seat back 102 rotates forward and over and onto the seat bottom 104. Inclusion of the bracket 106 allows the seat back to be displaced to a more forward position, thereby saving room within the bucket 152.
As illustrated in
By reducing the rearward footprint of the seat assembly 100 within the bucket 152 using the offset nature of the bracket 106, additional storage space is acquired and available for use within the vehicle behind the seat assembly 100 in stowed position B. The reduced packaging requirements by using the bracket 106 allow for a smaller bucket, or for storage of other items within the bucket. A more compact seat assembly 100 and smaller packaging space of the seat assembly 100 may also provide for reduced packaging of the seat assembly 100 if it is removed from the vehicle for storage.
This movement of the seat assembly between the use and stowed positions can be actuated either manually by the user or by a mechanically driven actuator or motor. In a preferred embodiment, the user simply presses a button (e.g. or a key fob, lever, dashboard . . . etc.) or other user impact and the seat assembly as a whole moves from the use position A to the stowed position B. When a user uses the seat assembly 100, the user actuates movement of the entire seat by means of a user input or a manual movement of the seat assembly 100. If the movement is manual, the seat back 102 will rotate towards the seat bottom 104 to a folded and stowed position. In some embodiments, the movement is automatic. The seat back 102 is moved either before actuation of the folding of the seat assembly 100 or while actuation of the folding of the seat assembly 100 is occurring (i.e. the movement as illustrated in
In some embodiments, the head rest is pivotally connected to the seat back 102. If the head rest is moved to a stowed position where the head rest is generally perpendicular to the seat back 102, even more packaging space is saved forward of the seat assembly 100 within the bucket 152.
The frame portions of the seat back 102 and the seat bottom 104 and the bracket 106 may be made of a metal, plastic, plastic like, polymer, and/or polymer like material sufficient to withstand the rigors required for the seat assembly 100. The legs 140, 142, 144 and the connection portions 146, 148 are similarly made of a metal, preferably a lightweight metal, or a polymer, polymer like, plastic, and/or plastic like material. Other components described herein may be made of similar materials or materials having similar properties.
The seat bottom portion 210 includes a distal end 214 having the main pivot axis 212. The seat back portion 208 includes a distal end 216 configured to connect to the seat back 202. The generally L-shaped bracket 206 includes a bend 215 to form the L-shaped configuration. While the present embodiment includes a generally L-shaped bracket 206, similar configurations and bends may also be provided to achieve the same result including varying angles and degrees between the seat bottom portion and the seat back portion.
As described above, the bracket 206 is generally L shaped have two distal ends 214, 216 spaced apart from a bend 215. In the some embodiments, the distal ends 214, 216 are rounded but may alternatively be squared off or any other suitable shape. In the present embodiment, the bend 215 includes an outer edge which is also curved or rounded to proceed an aesthetically appealing appearance. Alternatively, the bend 215 may be square or other suitable shape.
The distal end 216 of the seat back portion 208 of the bracket 206 connects directly to the seat back 202. The seat back 202 includes a proximal end 224 and a distal end 226. The distal end of the seat back portion of the bracket 206 connects directly to the proximal end 224 of the seat back 202. The distal end 226 of the seat back 202 may further include a head rest 228 having a pivot axis 230. In some embodiments, the head rest 228 is pivotable about the pivot axis 230 to provide for a more compact packaging during a stowed position.

Other components described herein may be made of similar materials or materials having similar properties.
During movement from the use position A to the stowed position G, the seat back 202 rotates forward and over and onto the seat bottom 204. Inclusion of the bracket 206 allows the seat back to be displaced to a more forward position, thereby saving room within the bucket 252.
As illustrated in
By reducing the rearward footprint of the seat assembly 200 within the bucket 252 using the offset nature of the bracket 206, additional storage space is acquired and available for use within the vehicle behind the seat assembly 100 in stowed position. The reduced packaging requirements by using the bracket 206 allow for a smaller bucket, or for storage of other items within the bucket. A more compact seat assembly 100 and smaller packaging space of the seat assembly 200 may also provide for reduced packaging of the seat assembly 200 if it is removed from the vehicle for storage.
This movement of the seat assembly is actuated either manually by the user or by a mechanically driven actuator or motor. In a preferred embodiment, the user simply presses a button (e.g. or a key fob, lever, dashboard . . . etc.) or other user impact and the seat assembly as a whole moves from the use position F to the stowed position G. When a user uses the seat assembly 200, the user actuates movement of the entire seat by means of a button or a manual movement. If the movement is manual, the seat back 202 will rotate towards the seat bottom 204 to a folded and stowed position. In some embodiments, the movement is automatic. The seat back 202 is moved either before actuation of the folding of the seat assembly 200 or while actuation of the folding of the seat assembly 200 is occurring (i.e. the movement as illustrated in
