Bench for utility automotive vehicle
A bench for a utility automotive vehicle, adapted to be installed transversely, in the front of a utility automotive vehicle, wherein the bench has a seat bottom framework and a seatback framework. The seat bottom framework comprises two lateral side plates, a first crosspiece and a second crosspiece with the first and second crosspieces each being fixed to each side plate. The seatback framework comprises at least two risers near the first crosspiece. Each riser is fixed to a respective side plate of the seat bottom framework such that in case of impact, the two risers come into contact with the first crosspiece in order to limit the deformation of the bench.
1 . A bench for a utility automotive vehicle, adapted to be installed transversely, in a front of the utility automotive vehicle, the bench comprising
a seat bottom framework and
a seatback framework,
wherein the seat bottom framework comprises two lateral side plates, a first crosspiece and a second crosspiece with the first and second crosspieces each being fixed to each side plate,
wherein the seatback framework comprises at least two risers near the first crosspiece,
wherein each riser is fixed to a respective side plate of the seat bottom framework so that during a front impact on the utility automotive vehicle, the two risers move to contact the first crosspiece in order to limit a deformation of the bench,
wherein a respective end of each riser extends substantially across from the first crosspiece, along a longitudinal direction of the bench, and in front of the first crosspiece, and
wherein the first crosspiece and each of the two risers are spaced apart such that the ends of the each of the two risers move towards and engage the first crosspiece during the front impact.
2 . The bench according to claim 1 , wherein a distance between the first crosspiece and each of the two risers is less than 50 mm, and the distance is configured to decrease during the impact.
3 . The bench according to claim 1 , wherein the seatback framework comprises a top crosspiece connecting the two risers.
4 . The bench according to claim 3 , wherein the top crosspiece and the at least two risers are unitary.
5 . The bench according to claim 3 , wherein the top crosspiece and the at least two risers are formed by distinct parts, fixed together.
6 . The bench according to claim 1 , wherein the at least two risers are tubular.
7 . The bench according claim 6 , wherein the at least two risers have a circular cross section.
8 . The bench according to claim 3 , wherein the top crosspiece is tubular.
9 . The bench according to claim 8 , wherein the top crosspiece has a circular cross section.
10 . The bench according to claim 1 , wherein at least one among the first crosspiece and the second crosspiece is cylindrical.
11 . The bench according to claim 1 , wherein at least one among the first crosspiece and the second crosspiece is tubular, with a square cross-section.
12 . The bench according to claim 1 , wherein each of the side plates of the seat bottom frame forms a housing for receiving a portion of a respective riser.
13 . The bench according to claim 1 , wherein the bench comprises a seatbelt support beam, secured to the first crosspiece.
14 . The bench according to claim 13 , wherein the seatbelt support beam is substantially halfway between the two risers.
15 . The bench according to claim 13 , wherein the seatback framework comprises a top crosspiece connecting the two risers and wherein the seatbelt support beam is secured to the top crosspiece.
16 . The bench according to claim 1 , wherein the seat bottom framework further comprises a stringer extending between the first crosspiece and the second crosspiece.
17 . The bench according to claim 1 , wherein the seat bottom framework comprises a base, forming a foot of the bench.
18 . The bench according to claim 17 , wherein the bench comprises a seatbelt support beam, secured to the first crosspiece, and wherein the base is secured to the seatbelt support beam.
19 . The bench according to claim 17 , wherein the seat bottom framework comprises a stringer extending between the first crosspiece and the second crosspiece, and wherein the base is secured to the stringer.
