Loss Function Curve to Quantify Customer (Dis)Satisfaction for Rear Chair Height (H30-2)

In vehicle design, the H point is a theoretical relative location measured in relation to specific characteristics that determines a group of dimensions to define vehicle interior roominess. Based on theoretical H point automakers concept their vehicle and have to make important decisions on vehicle architectural that could result in a bad product for the future customers and during the early phase of vehicle development, one of the key design attributes to consider is in relation to the interior comfort of the user, so that its design and its components enabling a favorable interaction with the occupant. Vehicle interior roominess is one of the key factors for buyers’ satisfaction with certain features such as the shoulder room, headroom and couple distance, among others, may influence the level of satisfaction of the occupants’ comfort. One of these items refers to the rear chair height (H30-2), which is presented while by the distance of rear H-point to the vehicle floor affecting the level of satisfaction for vehicle interior roominess. The objective of this project was to analyze the influence of the rear H point to vehicle floor in the vehicle interior roominess, and how the seat height can play an important role in the user’s perception. This study was supported by clinics, research and technical-statistical data.
