US Patent 7144079 Tailgate seat assembly

A seat assembly arranged to pivot about a horizontal axis and capable of being repositioned between a forward seated position and a tailgate position. The assembly includes a first assembly including a pin. The assembly further includes a second assembly including a recliner link. The recliner link is arranged to engage or disengage the pin based on rotation of the seat assembly. Engagement of the pin with the recliner link locks the seat assembly into tailgate position and prevents the first assembly from inadvertently folding into a position parallel to said second assembly.
