MS XIV is designed to accommodate 4 occupants and consequently will require 4 seats. Seat construction typically involves several components including a structural frame, padding, and additional upholstery. The seats for MS XIV are intended to be rigidly fixed to the vehicle chassis for the sake of simplicity and safety.

The range of occupant sizes and seating positions were previously determined in past terms. The aggressive seating angle (very low and laid back angle) and limited occupant size for rear occupants was chosen in order to meet the aerodynamic form-factor of the vehicle. See Occupant Cell Sizing (Key Document)

Several key considerations that should be made are: designing for minimal seat weight, designing for maximum cooling/ventilation of occupants (since solar cars have no air-conditioning system), and designing around ballast storage compartment (to ensure fairness, all occupants are given a ballast of lead-shot to be placed near the hips to bring their weight to 80kg/176lbs).

The scope of this project encompasses the entire design of both front and rear seats. This includes the structural aspect of the seat (typically composite), mounting of seat to chassis, padding, and fabric. An off-the-shelf 5-point safety harness will be used for all occupants and will be secured to the chassis via mounting tabs. The safety harness mounting will be handled by the aero-chassis team, however their placement will most likely be a joint effort with the interiors team.

A need exists for safe, comfortable, and lightweight seats for the front and rear occupants.

1. Have 4 complete and functional seats

2. Meets safety regulations (ASC and WSC)

3. Meets line-of-sight requirements for driver

4. Comfortable to sit in for a variety of users

5. Maximizes lightweight construction

6. Maximizes practicality

7. Aesthetically pleasing
