Claims19
A vehicle seat comprising:
- a back panel including a first polymeric matrix and a first plurality of bio fibers disposed therein;
- and
- a load carrier component attached to the back panel, the load carrier component including a second polymer matrix and a second plurality of bio fibers disposed therein, wherein the load carrier component includes a pair of curved or sigmoidal-shaped braided bio fiber tubes with bio fibers in each braided bio fiber tube being angled with respect to a longitudinal tube axis of the pair of curved or sigmoidal-shaped braided bio fiber tubes or wherein the load carrier component includes an open bio fiber shell embedded in the second polymer matrix, the open bio fiber shell including continuous biofibers that are substantially parallel to each other and to a longitudinal axis of the open bio fiber shell.
A vehicle seat comprising:
- a back panel including a first polymeric matrix and a first plurality of bio fibers disposed therein;
- and
- a load carrier component attached to the back panel, the load carrier component including a second polymer matrix and a second plurality of bio fibers disposed therein, wherein the load carrier component is integral with the back panel, the load carrier component including a pair of curved or sigmoid shaped 2-dimensional braided bio fiber shells embedded in the second polymer matrix with bio fibers in each bio fiber shell being continuous and substantially parallel to each other and optionally angled with respect to a longitudinal shell axis.
A vehicle seat comprising:
- a back panel including a first polymeric matrix and a first plurality of bio fibers disposed therein;
- and
- a load carrier component attached to the back panel, the load carrier component including a second polymer matrix and a second plurality of bio fibers disposed therein, wherein the load carrier component is integral with the back panel, the load carrier component including a pair of curved or sigmoid shaped bio fiber shell embedded in the second polymer matrix with continuous bio fibers in each bio fiber shell being substantially parallel to each other and optionally angled with respect to a longitudinal tube axis, the load carrier component including ribs disposed over a surface thereof.
