About this study

A descriptive study will be conducted to determine whether human subjects are able to install the new feature of the prototype car seat correctly. Participants will be presented with the prototype car seat and a set of basic written instructions and labels to guide their installations. The percentage of participants who use the new feature and use it correctly will be reported. Any installation errors on other parts of the child seat (seat belt, lower anchors, top tether) will also be reported.

    Number of participants who correctly install the load leg independently, without needing any prompt to use it.

  2. Attempt to Use Load Leg Without Prompting

    Time frame: 1 study visit, an average of 30 minutes

    Number of participants who noticed the load leg on their own, unfolded it from storage, and attempted to use it without being prompted by the researcher.

  3. Correct Load Leg Length

    Time frame: 1 study visit, an average of 30 minutes

    Number of participants who set the load leg to the correct length, including those who needed prompted to use it

  4. Correct Load Leg Angle
