First featured on the 2013 Nissan Altima® Sedan in the USA market, Nissan Zero Gravity seats design architecture has been incorporated in various vehicles throughout the lineup. This feature is unique for the Nissan lineup and not part of the Common Module Family CMF architecture of the Renault-Nissan-Mitsubishi Alliance group.
The Zero gravity seat concept gets its inspiration from the natural spinal posture, a neutral position body assumed in a weightless environment. In this posture, the least amount of stress is placed on our bones and joints, so the human body is less likely to become tired.
Engineers at Nissan used these findings to develop Zero Gravity Seats that have fundamentally changed the entire seat design to optimize comfort on longer drives. Nissan engineers have patented this structure
Nissan Zero Gravity Seats Concept
During long drives, the human body naturally slumps causing an increase in spinal bending to reduce muscle fatigue. This puts pressure on the lower back and leads to even more fatigue. To provide continuous support from hips all the way up to the shoulders, 14 different pressure points are identified and built into the seat to put the occupant in a neutral position. As per Nissan Engineering, this natural, ergonomic design helps to maximize blood flow and keep energy levels up.
Before Zero Gravity Seats were put into production, the seat concept went through extensive testing using a driving simulator, real-world long Distance and overnight evaluations, as well as biomechanical analysis. Testers included men and women of different heights and body types. Even medical tests were taken—like blood samples measuring lactic acidity levels—to confirm a reduction in muscular strain and fatigue.
Various vehicles throughout the Nissan lineup are equipped with this concept.
