Seat for armoured vehicle
View Patent ↗The invention relates to a seat ( 1 ) for an armored vehicle, incorporating a back rest ( 2 ) integral with a wall or the roof ( 4 ) of the vehicle and a sitting part ( 3 ) mounted able to pivot with respect to the back rest ( 2 ) between a folded position in which it is substantially parallel to the back rest ( 2 ) and an unfolded position where it is held by a limit stop and is substantially perpendicular to the back rest ( 2 ). This seat is characterized in that the sitting part ( 3 ) is connected to the back rest ( 2 ) by linking means ( 6, 8 ) ensuring, in the event of a predetermined load, the release of the limit stop ( 8 ) of the sitting part ( 3 ) and its pivoting beyond the unfolded position.
1. A seat for an armored vehicle, incorporating a back rest integral with a wall or the roof of the vehicle and a sitting part mounted able to pivot with respect to the back rest between a folded position in which it is substantially parallel to the back rest and an unfolded position where it is held by a limit stop and is substantially perpendicular to the back rest , such seat wherein the sitting part is connected to the back rest by linking means ensuring, in the event of a predetermined load, the release of the limit stop of the sitting part and its pivoting beyond the unfolded position, and wherein the sitting part is mounted able to pivot between two vertical supports, the linking means incorporating at least one protrusion forming a limit stop and cooperating with a stop surface integral with one of the supports, the profile of the protrusion, the stop surface, and the shape of the supports being selected so that the protrusion causes a deformation of the support when a predetermined load is exerted on the sitting part.
2. A seat according to claim 1 , wherein the supports are metallic plates, the stop surface is a rim fitted to a face of the plate that is facing the pivoting sitting part.
3. A seat according to claim 2 , wherein the plate includes a profile such that a load of a certain level exerted on the sitting part causes the plate to deform distancing the rim from the limit stop.
4. A seat according to claim 1 , comprising two protrusions each one of said protrusions cooperating with only one stop surface integral with one vertical support.
