A vehicle seat supporting body has padding which has a honeycomb body of elastic material and is covered with upholstery permeable to air and defining a user supporting surface; the cells of the honeycomb body extend along axes crosswise to the supporting surface, are open at the ends, and, in use, vary in volume in response to oscillating movement of the user; on the opposite side to the supporting surface, at least one opening connects the cells to the outside, and is opened/closed automatically by valves in response to compression and decompression of the air in the cells.

Vehicle seat supporting body

A seat portion of a vehicle seat has a padding, which is covered with permeable upholstery defining a user supporting surface and has a plurality of chambers extending crosswise to the supporting surface; the chambers are open at their ends and, in use, vary in volume in response to oscillating movement of the user; the chambers are grouped in at least four groups, which are located, respectively, in front right, front left, rear right, and rear left position; the chambers of each group are isolated in fluidtight manner by the chambers of the other groups and communicate with a respective opening, which connects the lower end of the chambers to the outside; the opening of each group is associated with a respective valve, which operates independently from the valves of the other groups and is opened/closed automatically in response to compression and decompression of the air in the chambers.

Seat portion of a vehicle seat

A lumbar support for a vehicle backrest has a rest member with a front surface shaped to support an area of a user's back, and an elastic member behind the rest member; the elastic member has an intermediate portion fixed to the rest member and two opposite ends fixed connected to a backrest frame, maintains the rest member in a rest position and can deform in response to a thrust of the user's back so as to let the rest member move between the rest position and a first position under normal conditions, and then abruptly towards a second position when a thrust of a user's back exceeds a given force value; the force/displacement curve of the elastic member has a slope which is between zero and a given threshold in the section between the first and the second positions, the threshold being equal to 0.5 [N/mm].

Lumbar support for a vehicle backrest

A seat body for vehicles has a padding made of plastic material foam and provided with through holes; the padding is covered by an upholstery covering having a fabric layer and a hygroscopic layer, which are heat-fixed together; the fabric layer defines a support surface for a user, while the material of the hygroscopic layer is an open-cell polyurethane foam having a cell mean linear density less than or equal to 15 cell/cm.

Support body of a seat for vehicles

A lumbar support for a vehicle backrest has a resting element with a front surface shaped for supporting an area of the back of a user; the resting element is connected to a frame of the backrest via elastic elements, which are bistable for allowing the resting element to click from an advanced position to a rearward position when a thrust against the front surface exceeds a given threshold.

A chair or a seat, in particular a seat for motor vehicles, includes an ergonomic device for supporting the body of the occupant, comprising a supporting panel having supporting laths, set at a distance from one another, which can be arched towards the body of the occupant, each independently of the others, by a respective actuator, which includes an actuator element constituted by a shape-memory material, which undergoes a reduction in length following upon heating above a predetermined transition temperature, higher than ambient temperature. Associated to the panel are electrical-supply means for supply of the shape-memory actuators and electronic control means for activating the laths independently and/or in succession according to any predetermined logic, in particular according to successive waves of activation, for example from above downwards, or from below upwards, or alternately from above and from below, so as to obtain a massaging effect.
