Compounds of the general structural formula (I) and (II) and use of the compounds and salts and hydrates thereof, as therapeutic agents are disclosed. Treatable diseases and conditions include cancers, inflammatory diseases and conditions, and immunodeficiency diseases. (I), (II).

A folding chair may include a frame that is configured to transition the folding chair between use and storage positions. A seat base may be pivotally coupled thereto at a first particular length from a front end and a receiving portion may be disposed in an upper surface. The receiving portion may include left and right lateral edges, front and rear longitudinal edges, and a depth. The padding material may be disposed in the receiving portion and may have a lateral dimension related to a distance between the front and the rear longitudinal edges, a longitudinal dimension related to a distance between the front and the rear longitudinal edges, and a thickness related to the depth. The padding layer may cover a majority of a top surface of the padding material and of the upper surface. The cover may retain the padding material and the padding layer relative to the seat base.

A height adjusting structure with directly communicating airbags includes at least two airbags, where the airbags each receive and retain therein an elastic body. One of the airbags includes an air control unit connected thereto for controlling air filling and discharge of the airbags. The airbags are provided, in surfaces thereof that opposes each other, with corresponding passage holes and joint sections formed around circumferences of the passage holes. The joint sections are jointed so that the airbags are directly connected with no additional medium between the airbags and allowing the airbags to share the same air control unit to achieve flowability of air between the airbags, whereby advantages of efficient air filling and discharge of the airbags, being easy to manufacture, and reducing manufacture costs can be achieved.

A vehicle seat includes a seat bottom (16) and a seat back (18) extending upwardly from the seat bottom. The seat back (18) includes a backrest and a backrest cover (28) coupled to the backrest, said backrest including a backrest frame (26) made from composite materials.

A fluid-fillable cushion comprises upper and lower layers, a first chamber and a second chamber and a discrete pressure distributing unit situated between the upper and lower layers, said pressure distributing unit providing a fluid connection between at least the first chamber and the second chamber. Such a cushion reduces leaks and allows controlled pressure equalisation between the chambers. Also disclosed is a process for making such cushions and seating products comprising such cushions.

The molded surface fastener has a plurality of engaging regions having engaging elements and a plurality of space regions disposed between the engaging regions. Each space region has a plurality of wall pieces standing on a substrate portion and intrusion-accepted space portions which allows a foam resin material to intrude across the wall pieces in foam molding of a cushion body. By that, deformation or breakage of the engaging element in a manufacturing process can be prevented. Moreover, the molded surface fastener is firmly fixed in a state that the engaging elements are exposed.
