CAVA Manikin
Determine occupant seating positions and verify SAE parameters with a two-dimensional test dummy
The SAE Standards specify a two-dimensional test dummy for use in determining the various occupant seating positions. CAVA Manikin allows the dummy to be positioned according to the geometric guidelines or by specifications for the joint angles of the body and the relevant parameters. Using the contours of the head position, handreach envelopes, and the eye viewpoints and ellipses, all relevant SAE parameters, such as headroom, handreach or legroom, can be verified.
Why do you need CAVA Manikin?
Save time determining the correct seating positions of occupants
Easily create standard eyepoint and eyellipses to be used in vision analysis
Quickly measure key parameters for head room clearance to the roof
Ensure headrests meet required safety qualities

Key Features & Capabilities
SAE 2D Manikin Template
- Provide practical positioning methods for specific purposes as described in SAE J826 standard.
- Define the seating reference point based on heel, floor and pedal reference point and/or recommended joint angles.
- Define pedal geometry and heel point based on seating reference points, floor geometry and joint angles.
- Measure legroom in the rear seats (long-coupled and short coupled situation).
- Check for clash with geometry (front seat, dashboard, etc.).
- Provide SRP location curves SAE J4004 as reference.
Head Room Measurement
Calculate the headroom clearance to the roof in vertical and diagonal directions according to SAE J1052.
Head Rest Verification
- Calculates the backset and height as measured with the headrest measurement device (HMD) according To FMVSS 202 and NCAP.
- Checks if the required width, height and roof clearance of a headrest is achieved.
Eye Points/Ellipses
- Creates the standard eyepoints according to UNECE-R 125 for different purposes in vision and mirror analysis.
- Creates the ellipses according to SAE J941 as required for FMVSS vision checks. Supports different definitions based on standard year and purpose.

What Our Customers Think..
The implementation of CAVA at Ford Motor Company started in 2007 and was seamlessly integrated into the global company system of CATIA V5. Today, about 100 CAVA users around the world work with the software for global product management in the US, Brazil, Germany, UK, Turkey, Australia, China and India. It is rolled out in several departments.
In a recent project, we saved close to 1000 design hours versus traditional methodologies in the first year alone thanks to CAVA Vision.
