For this project we are being asked by Lockheed Martin to design a reconfigurable seat for their Humvee/Truck VCCT. For this project, we need to design a simple and robust seat that that can wistand the rigors or use by a 95th percential (250lb) soldier. It needs to be durable and designed to last for several years of uninterrupted use in a combat scenerio. These VCCT's are traditionally parked as bases and used regually for training.

The seat also needs to be able to changed directions a complete 180 degrees, have ~4'' of fore and after travel, as well as 4'' of up and down travel. All of these adjustments need to be stout and able to be quickly modified without the use of tools. A final requirement is that the seat needs to be able to withstand a 70lb horizontal load placed on the back portion of the seat. This is primarily where the original design failed. The students are expected to design the seat as well as build a fully functional prototype for display at the Senior Design Competition. Finally, the students will be asked to make several interim presentations outlining the progress of their work, as well as experiencing the pitfalls and process of the entire design process. We have a reconfigurable simulator for the services that in one direction it is a Humvee and when facing the other direction it is a truck. The problem is the seat needs to adjust front and back for leg room and the back of the seat needs to change directions depending on the direction the person is facing. The current design we have can not support a 250 lb soldier and we have many bent and broken seats in the field. I have asked the team to provide me with top level requirements so I can pass on. To get started the team should think about how to change the seat from front to back without any special tools, able to support a 250 lb person exerting force along the back of the seat to get out of the vehicle, adjust the seat from front to back, simple assembly in production. I will send more when I get back in the office on Monday.
