In a vehicle seat pad 1, a seating portion has a plurality of bottomless or bottomed holes 10h, and in a horizontal projection plane, a ratio R11U of a total area of under-femoral-region holes in an upper surface of a femoral region-placed portion with respect to an entire area of the femoral region-placed portion, a ratio R12CU of a total area of under-hip holes in an upper surface of an under-hip center portion with respect to an entire area of the under-hip center portion, and a ratio R12SU of a total area of under-hip holes in upper surfaces of a pair of under-hip side portions with respect to entire areas of the pair of under-hip side portions satisfy R11U>R12 CU>R12SU.

A suspension mat (14) for a vehicle seat comprises one or more suspension springs (16) for supporting a cushion (28), a support plate (18) attached to the one or more suspension springs, a mobile plate (34) coupled with the support plate, a flat spring (26) arranged between the support plate and the mobile plate and a switch element. The mobile plate is arranged movable between a first and a second position relative to the support plate. The flat spring biases the mobile plate toward the first position. The switch element is located between the support plate and the flat spring, in such a way that when the mobile plate moves against a bias of the flat spring toward the second position, the flat spring presses and actuates the switch element. The flat spring may e.g. comprise a washer spring, a plate spring, a dome-shaped flat spring and/or a cantilever flat spring.

A seat attachment assembly for attaching components to a seat cushion is provided. A central base has at least one footing with an opening adapted for being encapsulated in the cushion. A cylindrical shaft extends generally perpendicular from the central base and defines a cylindrical opening therein. A retention clip has an extension portion sized to be received and retained in the cylindrical opening by an interference fit.

A seating system for a vehicle has a positioning insert configured for attachment at a predetermined location to a portion of a seat cushion arrangement forming a part of the seating system such that the positioning insert facilitates positioning a seated occupant at a desired fore-aft position. The positioning insert may include a first side having a generally arcuate portion configured to be oriented toward a seated occupant and to receive a seated occupant's buttocks to facilitate positioning of the seated occupant at the desired fore-aft position.

Realized is a vehicle seat capable of improving the rigidity of a cushion frame with respect to a load input to a seat back while suppressing an increase in weight and size of the cushion frame. In a vehicle seat including a height adjustment mechanism which is driven to adjust the height of a seat cushion and a brake mechanism which maintains the height of the seat cushion when the height adjustment mechanism is not driven, the brake mechanism is connected to a second connection portion different from a first connection portion connected to the seat back in the cushion frame, and reinforcement portions and which extend in a direction from the first connection portion toward the second connection portion are provided between the first connection portion and the second connection portion in the cushion frame.

An adjustable suspended seat apparatus having a tuned frequency-tailored damping through stratified seat structure is described. The damping seat structure includes: a first material of a plurality of materials having a first characteristic to provide a first damping effect in a first layer. A second material of the plurality of materials based on a second characteristic to provide a second damping effect in a second layer, the first material or the second material having an adjustable damping characteristic. The suspended seat apparatus includes a seat base configured to have the seat coupled thereto; a suspension system coupled to the seat base, the suspension system comprising: an adjustment feature configured to adjust operation of the suspension system; and a chassis mount coupled to the suspension system, the chassis mount configured to be coupled to a vehicle.
