This application claims the benefit of Chinese Utility Model Patent Application No.: CN 201320728158.1, filed Nov. 18, 2013, the entire contents thereof being incorporated herein by reference.
The present invention in one or more embodiments relates to a seatback stabilization device and a vehicle employing the same.
For vehicles, contents of the trunk storage may engage in forward movement in the event of a sudden stop. To prevent the mounting frame of a seatback from tilting forward due to the impact, and hence to reduce injuries to the vehicle occupant, it may be desirable to provide relatively enhanced stabilization to the seatback in case of such an impact.
U.S. Patent U.S. Pat. No. 8,356,860 discloses a collapsible vehicle seat fixed to a vehicle body by releasable lock and structure. In particular, a pin may be inserted into a recess, and then strikes a latch to cause the latch to turn to a locking position to lock. Such structures tend to be complicated, and the operation of such a releasable latch structure can be cost prohibitive and therefore not necessarily suitable for vehicle rear seats that do not need to be foldable.
In certain existing designs, and for vehicle rear seats which do not need to be foldable, the vehicle rear seats may be installed via connecting three hook members welded onto a mounting frame of the rear seat to a circular member of a stabilization panel such that the mounting frame may be connected to the stabilization panel. Because the three hook members are not durable enough, and the vehicle stabilization panel is not load-bearing and hence not durable enough to sustain impact coming from the rear, it is often needed to install two additional tubular members to provide additional strength.
In one or more embodiments, a vehicle seatback stabilization device includes a seatback stabilization portion to be connected to a seatback, and a vehicle body connection portion including an aperture to receive a connector of a vehicle body load-bearing structure.
The seatback stabilization portion may include first and second stabilization panels positioned with an angle relative to each other. The vehicle body connection portion may extend away from the second stabilization panel such that the second stabilization panel is positioned between the first stabilization panel and the vehicle body connection portion. The first stabilization panel and the vehicle body connection portion may extend from two opposing edges of the second stabilization panel, respectively. The vehicle body connection portion may be positioned relative to the second stabilization panel with an angle.
The seatback stabilization portion may further include a pair of side walls for clamping a seatback mounting frame of the seatback. The pair of side walls may each define an aperture thereupon. The pair of side walls may each define thereupon first and second apertures extending in two different directions. The vehicle body load-bearing structure may include a vehicle cargo compartment reinforcement structure.
The vehicle body connection portion may further include a cushion sleeve to be received through the aperture and positioned between the arm of the vehicle body load-bearing structure and an inner surface of the aperture.
One or more advantageous features as described herein will be readily apparent from the following detailed description of one or more embodiments when taken in connection with the accompanying drawings.
For a more complete understanding of one or more embodiments of the present invention, reference is now made to the one or more embodiments illustrated in greater detail in the accompanying drawings and described below wherein:
As referenced in the FIGS., the same reference numerals are used to refer to the same components. In the following description, various operating parameters and components are described for different constructed embodiments. These specific parameters and components are included as examples and are not meant to be limiting.
The present invention in one or more embodiments is believed to be advantageous in providing a seatback stabilization device to secure and stabilize a seatback when the vehicle comes to sudden deceleration or a stop. The seatback stabilization device includes a seatback stabilization portion to be connected to a seatback and a vehicle body connection portion with an aperture to receive a connector of a vehicle body load-bearing structure. In certain embodiments, the vehicle body load-bearing structure includes or may be a cargo reinforcement structure of the vehicle. Thus, the seatback may be indirectly and securely connected to the rather stable cargo reinforcement structure via a connection of the vehicle body connection portion and the seatback stabilization portion.
The present invention in one or more embodiments is believed to be advantageous further in providing a relatively simple mechanism by which the vehicle rear seatbacks may be stabilized in an event of sudden deceleration or a stop. The simple design also facilitates its versatile employment in various vehicle types and hence the realization of enhanced cost efficiency.

The vehicle body load-bearing structure 2 may be any suitable vehicle body load-bearing structure, and in certain embodiments may be a vehicle cargo compartment reinforcement structure.
In certain existing designs, vehicle rear seats may be directly connected to vehicle rear storage support frames, which are then connected to vehicle load-bearing structures such as vehicle cargo compartment reinforcement structures. In these instances, the vehicle rear storage support frames are often formed of non-metal materials and are connected to the vehicle body indirectly via the vehicle cargo compartment reinforcement structures, and therefore are only provided with limited resistance to any impact coming from the rear. Accordingly, additional reinforcement structures may be needed to relatively ensure the vehicle rear seats are resistant to impactful forces.
The vehicle load-bearing structure 2 may be directly connected to or itself includes a vehicle cargo compartment reinforcement structure for supporting storage frames or other similar vehicle load bearing structures. In this connection, and because the vehicle cargo compartment structure is directly connected to the vehicle steel frames via welding or other known methods, the connection is stable and secure and does not necessarily require additional rear storage support frames. Referring back to
In summary, the seatback stabilization device 100 includes the vehicle body connection portion 5 to be connected to the vehicle cargo compartment reinforcement structure for supporting storage frames, and the seatback stabilization portion 4 to be connected to the seatback mounting frame 1. Therefore via a connection between the seatback stabilization portion 4 and the vehicle body connection portion 5, the vehicle seatback mounting frame 1 is securely connected to the vehicle cargo compartment reinforcement structure. Because the vehicle cargo compartment structure is directly connected to the vehicle steel frames via welding or other known methods, the connection is stable and secure and does not necessarily require additional rear storage support frames. Accordingly, the vehicle may be provided with relatively reduced complexity and enhanced cost efficiency.
In addition, and because the connector 9 of the vehicle body load-bearing structure 2 extends out and is received through the aperture 6 via an angled configuration, the connector 9 with the angle configuration may exert an effective pulling on the seatback stabilization portion 4 against a force due to sudden deceleration or a stop. Accordingly the connection between the seat stabilization portion 4 and seatback mounting frame 1 is enhanced.
The present invention in another or more embodiments also provides a vehicle which includes the seatback stabilization device 100 described herein elsewhere. With the seatback stabilization device 100, the vehicle rear seats may be relatively more stabilized in resisting impact from the rear storage when the vehicle decelerates or comes to a sudden stop.
Of course, the vehicle seatback stabilization device 100 does not have to be limited to the configurations described and depicted herein. For instance, the connector 9 may be provided with any suitable structures or configurations. However, the seatback stabilization device 100 may be mainly used for rear seats with pre-fixed positions, in which the connector 9 may be alternatively used in vehicles with 6/4 foldable seats. Therefore both pre-fixed rear seats and 6/4 foldable seats may adopt the same connector 9 for carrying out the stabilization, so as to bring additional efficiencies in design, molding and processing.
In one or more embodiments, the present invention as set forth herein is believed to have overcome certain challenges in achieving reasonable amount of vehicle rear seatback stabilization. However, one skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims that various changes, modifications and variations can be made therein without departing from the true spirit and fair scope of the invention as defined by the following claims.
