  • Publication number: 20200001753
    Abstract: Vehicle seat fixed to the floor of a cabin of a vehicle and which is able to absorb the impact of a passenger seated behind. It comprises at least two uprights (20) per backrest, these being positioned substantially vertically and engaged via a lower end (30) in the fixed framework (32) of the seat in such a way as to be releasable through upward translational movement so that they can disengage upward under the effect of an impact on a rear face, and are mounted with the ability to rotate about at least one fixed axis of the fixed framework (32) so as to be able to pivot forwards after becoming disengaged. At least one deliberate mechanical weak link positioned between each upright (20) and the framework (32) blocks the translational movement of the upright below a determined force corresponding to the impact. Application to aircraft seats.
