a comfort section arranged for engagement with a user's body seated on the vehicle seat, the comfort section including a resilient cushion for compression under load of the user's body; and a collapsible support that provides support to the comfort section, wherein the collapsible support includes at least one precision safety section configured for failure to permanently collapse in response to a predetermined change in momentum to enable at least a portion of a connection structure to penetrate at least one cavity to reduce impulse between the vehicle seat and the user's body under vehicular collision. ### Claim 2 (depends on 1) The vehicle seat of claim 1, wherein the collapsible support includes a safety matrix layer for providing collapsible support to the comfort section, the safety matrix layer including an engagement platform connected with one of the frame and the comfort section, and a collapsible safety structure secured with the engagement platform, the collapsible safety structure including at least one connection structure and at least one cavity, the at least one connection structure connected with the engagement platform and including the at least one precision safety section configured for failure to permanently collapse at the predetermined change in momentum to enable the at least a portion of the connection structure to penetrate the at least one cavity to reduce impulse between the vehicle seat and the user's body under vehicular collision. ### Claim 3 (depends on 2) The vehicle seat of claim 2, wherein the safety matrix layer is arranged within a center section of a backrest of the vehicle seat. ### Claim 4 (depends on 3) The vehicle seat of claim 3, wherein the vehicle seat includes a body having a base and the backrest extending vertically from the base, wherein the comfort section includes a first section forming a portion of the base and a second section forming a portion of the backrest. ### Claim 5 (depends on 2) The vehicle seat of claim 2, wherein the safety matrix layer is arranged within an exterior trim layer such that collapse of the at least one precision safety section to penetrate the at least one cavity with at least a portion of the connection structure maintains the safety matrix layer within the exterior trim layer without protrusion outside of the exterior trims layer. ### Claim 6 (depends on 2) The vehicle seat of claim 2, wherein the at least one connection structure is one of a network of connection structures included in the collapsible support. ### Claim 7 (depends on 6) The vehicle seat of claim 6, wherein the network is formed as an additive structure having a single integral member forming a plurality of connection structures of the network. ### Claim 8 (depends on 6) The vehicle seat of claim 6, wherein the network forms a lattice structure. ### Claim 9 (depends on 8) The vehicle seat of claim 8, wherein the at least one cavity is defined by space formed between adjacent portions of the lattice structure. ### Claim 10 (depends on 2) The vehicle seat of claim 2, wherein collapsing the at least one precision safety section includes at least one of deforming and breaking the at least one precision safety section. ### Claim 11 (depends on 1) The vehicle seat of claim 1, wherein the comfort section includes an exterior trim layer defining an outer portion of the vehicle seat for contact with the user. ### Claim 12 A transportation vehicle comprising: a chassis; a body mounted to the chassis; a safety seat secured with the body for supporting a user in the seated position, the safety seat including a frame for attachment with the body, a comfort section arranged for engagement with a user's body seated on the vehicle seat, the comfort section including a resilient cushion for compression under load of the user's body and a collapsible support that provides support to the comfort section, wherein the collapsible support includes at least one precision safety section configured for failure to permanently collapse in response to a predetermined change in momentum to enable at least a portion of a connection structure to penetrate at least one cavity to reduce impulse between the vehicle seat and the user's body under vehicular collision. ### Claim 13 (depends on 12) The transportation vehicle of claim 12, wherein the collapsible support includes a safety matrix layer for providing collapsible support to the comfort section, the safety matrix including an engagement platform connected with one of the frame and the comfort section, and a collapsible safety structure secured with the engagement platform, the collapsible safety structure including at least one connection structure and at least one cavity, the at least one connection structure connected with the engagement platform and including the at least one precision safety section configured for failure by permanently collapsing at the predetermined change in momentum to enable the at least a portion of the connection structure to penetrate the at least one cavity to reduce impulse between the vehicle seat and the user's body under vehicular collision. ### Claim 14 (depends on 13) The transportation vehicle of claim 13, wherein the safety matrix layer is arranged within a center section of a backrest of the safety seat. ### Claim 15 (depends on 14) The transportation vehicle of claim 14, wherein the safety seat includes a seat body having a base and the backrest extending vertically from the base, wherein the comfort section includes a first section forming a portion of the base and a second section forming a portion of the backrest. ### Claim 16 (depends on 13) The transportation vehicle of claim 13, wherein the comfort section includes an exterior trim layer defining an outer portion of the safety seat for contact with the user. ### Claim 17 (depends on 13) The transportation vehicle of claim 13, wherein the safety matrix layer is arranged within the exterior trim layer such that collapse of the at least one precision safety section to penetrate the at least one cavity with at least a portion of the connection structure maintains the safety matrix layer within the exterior trim layer without protrusion outside of the exterior trims layer. ### Claim 18 (depends on 13) The transportation vehicle of claim 13, wherein the at least one connection structure is one of a network of connection structures included in the collapsible support. ### Claim 19 (depends on 18) The transportation vehicle of claim 18, wherein the network is formed as an additive structure having a single integral member forming a plurality of connection structures of the network. ### Claim 20 (depends on 18) The transportation vehicle of claim 18, wherein the network forms a lattice structure. ### Claim 21 (depends on 20) The transportation vehicle of claim 20, wherein the at least one cavity is defined by space formed between adjacent portions of the lattice structure. ### Claim 22 (depends on 13) The transportation vehicle of claim 13, wherein collapsing the at least one precision safety section includes at least one of deforming and breaking the at least one precision safety section.
