A vehicle seat may include a seat back that has a back frame, a cushion pad attached to the back frame, and a massaging unit having a plurality of massaging elements. The cushion pad has a plurality of through bores that pass therethrough in the direction of thickness thereof. The massaging elements are constructed so as to be elastically deformed or compressed along moving axes and to be pneumatically expanded and contracted along the moving axes. The massaging elements are disposed in the through bores in a manner that the moving axes of the massaging elements extend along longitudinal axes of the through bores. The massaging elements have deformability or compressibility identical with or greater than the deformability or compressibility of the cushion pad when the massaging elements are not operated.

The invention claimed is: 1. A vehicle seat having a seat back, the seat back comprising: a back frame, a retainer spring arranged in the form of a wire that extends transversely within the back frame, the retainer spring including a central portion that projects rearwardly, a cushion pad attached
The invention claimed is: 1. A vehicle seat having a seat back, the seat back comprising: a back frame, a retainer spring arranged in the form of a wire that extends transversely within the back frame, the retainer spring including a central portion that projects rearwardly, a cushion pad attached to the back frame, the cushion pad having a plurality of cylindrical through bores that pass therethrough in the direction of thickness thereof, and a massaging unit having a plurality of massaging elements, the massaging elements being constructed so as to be elastically deformed or compressed along moving axes and to be pneumatically expanded and contracted along the moving axes, wherein the massaging elements are formed as corrugated hollow members, wherein the massaging elements include massaging end portions, each massaging end portion having a circular shape that substantially corresponds with the cross-sectional shape of a corresponding one of the cylindrical through bores, wherein the massaging elements are disposed in the cylindrical through bores in a manner that the moving axes of the massaging elements extend along longitudinal axes of the cylindrical through bores, wherein the massaging elements are disposed on the central portion of the retainer spring, so as to be attached to the back frame via the retainer spring; and wherein the massaging elements have deformability or compressibility identical with or greater than the deformability or compressibility of the cushion pad when the massaging elements are not operated. 2. The vehicle seat as defined in claim 1 further comprising an actuator that is in fluid communication with the massaging elements via air pipes, and connector units that can interconnect the air pipes and the massaging elements, each of the connector units comprising a first connector element having a first connecting portion that can be connected to the massaging element, and a second connector element having a second connecting portion that can be connected to the air pipe, wherein the massaging elements are attached to the back frame via an attachment member, and wherein the first and second connector elements of each of the connector units are arranged and constructed such that the first and second connecting portions can be positioned on opposite sides of the attachment member. 3. The vehicle seat as defined in claim 2, wherein the first and second connector elements of each of the connector units are arranged and constructed such that the first and second connecting portions can respectively extend along the attachment member. 4. The vehicle seat as defined in claim 3, wherein each of the massaging elements has a connecting projection that extends along the attachment member. 5. The vehicle seat as defined in claim 2, wherein the first connecting portion extends from a first body portion of the first connector element, wherein the second connecting portion extends from a second body portion of the second connector element, and wherein the second body portion is rotatably coupled to the first body portion so that the second connecting portion can rotate relative to the first connecting portion. 6. The vehicle seat as defined in claim 1, wherein the moving axes of some of the massaging elements are directed to a direction different from the direction of the moving axes of the remaining massaging elements. 7. The vehicle seat as defined in claim 6, wherein the moving axes of the massaging elements positioned on an upper side of the back frame are directed more downwardly than the moving axes of the massaging elements positioned on a lower side of the back frame. 8. The vehicle seat as defined in claim 7, wherein the back frame is divided into an upper frame portion and a lower frame portion, and wherein the upper frame portion can be tilted back and forth relative to the lower frame portion. 9. The vehicle seat of claim 1 further comprising an attachment plate disposed between the retainer spring and the massaging elements. 10. A vehicle seat having a seat back, the seat back comprising: a back frame, a retainer spring arranged in the form of a wire that extends transversely within the back frame, the retainer spring including a central portion that projects rearwardly, a cushion pad attached to the back frame, the cushion pad having a plurality of cylindrical through bores that pass therethrough in the direction of thickness thereof, and a massaging unit having a plurality of corrugated hollow members that are attached to the back frame via upper and lower attachment plates, the corrugated hollow members being constructed so as to be elastically deformed or compressed along moving axes; an actuator in fluid communication with the corrugated hollow members via air pipes so that the corrugated hollow members can be pneumatically expanded and contracted along the moving axes, and connector units disposed between the air pipes and the corrugated hollow members, each of the connector units comprising a first connector element having a first connecting portion that can be connected to the corrugated hollow member, and a second connector element having a second connecting portion that can be connected to the air pipe, wherein each of the corrugated hollow members include a lid portion having a circular shape that substantially corresponds with the cross-sectional shape of a corresponding one of the cylindrical through bores, wherein the corrugated hollow members are disposed in the cylindrical through bores in a manner that the moving axes of the corrugated hollow members extend along longitudinal axes of the cylindrical through bores, wherein the massaging elements are disposed on the central portion of the retainer spring, so as to be attached to the back frame via the retainer spring, wherein the first and second connector elements of each of the connector units are arranged and constructed such that the first and second connecting portions can be positioned on opposite sides of the attachment member, and wherein the moving axes of the corrugated hollow members attached to the back frame via the upper attachment plate are directed downwardly than the moving axes of the corrugated hollow members attached to the back frame via the lower attachment plate. 11. The vehicle seat of claim 10 wherein the upper and lower attachment plates are disposed between the retainer spring and the massaging elements.
