The dimensions of footrests, armrests, and headrests are important aspects in car seat design. If any of these components have incorrect dimensions, the seat may be uncomfortable or even dysfunctional. Therefore, this article will discuss the dimensions of car footrests, armrests, and headrests based on anthropometric data.

Anthropometric Dimensions of Footrests, Armrests, and Headrests in Cars
Footrest dimensions are used to determine the length of the footrest based on knee height. Armrest dimensions are used to determine the length and height of the armrest. The headrest dimension of a car is the dimension used to measure the height of the headrest. To determine the dimensions of each component of the car seat or upholstery, starting from the footrest, armrest, and headrest dimensions, it is important to know the anthropometric dimensions that are taken to obtain the dimensions that will be presented later. The following are the anthropometric dimensions:

Dimension Information:
- A: Knee Length
- B: Popliteal Length
- C: Sitting Elbow Height
- D: Sitting Shoulder Height
- E: Sitting Height
- F: Popliteal Height
- G: Forearm Length
- H: Knee Height
- I: Hip Width
