      <p class="para_topic">Envelope boundaries define hand control locations that can be reached in passenger cars, multi-purpose passenger vehicles, and light and medium trucks.</p>
      <p class="para_topic">Hand reach envelopes can be created for six different seat configurations: three male to female driver population ratios with two types of restraint systems. These include drivers wearing only a lap belt to permit free upper torso and unrestrained reach, and drivers wearing a lap and shoulder belt permitting restrained reach. </p>
