BACKGROUND OF THE INVENTION

1. Technical Field


The disclosure generally relates to adjustable seats and mounts therefor. In particular, the instant disclosure relates to an upper seat mount for adjustable seats, like in automobiles.


2. Description of Related Art


Adjustable seats, as used herein, are seats that can at least be adjusted from forward to backward to adjust for comfort and positioning of various sized users. Typically, an adjustable seat is mounted at the bottom of the seat on tracks or rails. A seat lock may be positioned on the rails to lock the seat in a desired position. For example, the user can lift a handle underneath the seat to disengage the seat lock and slide the seat back and forth to the desired position.


One problem that has been discovered with adjustable seats is over time the top of the seats begins to flex increasingly more as the lower seat mounts wear. This flex in the top of the seat may be problematic for obvious safety reasons in addition to comfort of the driver. One solution to this wear problem has been to mount the upper portion of the seat solid to the frame that supports the adjustable seat, like the car chassis/body. However, this solution eliminates or drastically reduces the user's ability to adjust the seat. For example, fore and aft movements can only be made by removing and replacing the mount/strap at the top of the seat.


Another problem with adjustable seats is the limited protection from side impacts, which is further restricted the higher up the seat the impact occurs (i.e. the more distance from the underneath seat mount). Again, this limited protection is more problematic with additional flex in the top of the seats as the lower seat mounts wear.


Therefore, it is readily apparent that there is a recognizable unmet need for an upper seat mount for adjustable seats that provides support to the top portion of the seat while maintaining the adjustability of the seat.


SUMMARY

Briefly described, in a preferred embodiment, the present apparatus and method overcomes the above-mentioned disadvantages and meets the recognized need for such a device by providing an upper seat mount for an adjustable seat capable of providing support to the top portion of the seat while maintaining the adjustability of the seat.
