A rigid back member of an automatic mechanical chest compression device is secured to a torso support platform. The torso support platform includes a main support strap immediately below where the rigid back member is secured to the torso support platform, and an upper support strap above where the rigid back member is secured to the torso support platform. The torso support platform tapers towards the top at approximately where a patient's shoulders are located when properly secured to the torso support platform. Additional straps may also be utilized, for example, shoulder straps extend over the shoulders of the patient and are secured to the torso support platform at a point below the patient's armpits, or straps that extend from the tapered section and secure to the automatic mechanical chest compression device.
