A first axial region (71) and second axial region (72) of the substantially U-shaped end portion (7 a) of the at least one spring (7) are adapted to be engaged with the inner spring engagement piece (61) and the outer spring engagement piece (62), respectively, whereby the end portion of the at least one spring is adapted to be fixed to the round shaft through the attaching device.
Description
- The present invention relates to an attaching device for fixing end portions of springs to be stretched between opposing frame sections of a seat cushion frame for a seat and, more particularly, to an attaching device for fixing end portions of springs, each of which has a substantially U-shape in outline, to a round shaft which is employed as a frame section constituting one of opposing frame sections of a seat cushion frame for a seat.
- As a vehicle seat, there has been proposed a vehicle seat in which a metal-made round shaft is employed as a rear frame section of a seat cushion frame for the seat, zigzag springs for supporting a cushion thereon are stretched between the round shaft and a forward frame section of the seat cushion frame, and end portions of the zigzag springs are fixed to the round shaft by a retainer (Japanese Patent Application Laid-Open No. 2006-14867).
- The retainer comprises a longitudinal body of a substantially U-shape in cross-section, and pairs of first and second spring engagement pieces provided at both longitudinal edges of the longitudinal body so as to be spaced apart from one another along the longitudinal edges, the first spring engagement pieces being bent laterally outwardly from one of the longitudinal edges of the longitudinal body and the second spring engagement pieces being bent laterally outwardly from the other of the longitudinal edges of the longitudinal body. The longitudinal body and the pairs of first and second spring engagement pieces are integrally formed from a metal plate by causing the metal plate to be bent. The retainer is adapted to be mounted on the round shaft with the substantially U-shaped longitudinal body being fitted over the round shaft, with the first spring engagement pieces being located inside the seat cushion frame, and with the second spring engagement pieces being located outside the seat cushion frame. Each of the end portions of the springs is formed substantially in a U-shape in outline and comprises first and second spaced apart axial regions and an intermediate axial region interconnecting the first and second spaced apart axial regions. The end portion of a spring is fixed to the round shaft through the retainer, with the first axial region and the second axial region being heldly engaged with a corresponding first spring engagement piece and a corresponding second spring engagement piece of the retainer, respectively, and with the intermediate axial region being located under the round shaft and engaged with the round shaft.
- An inner circumference of the substantially U-shaped longitudinal body of the retainer is dimensioned such that the longitudinal body can be fitted over an outer circumference of the round shaft. Therefore, when the zigzag springs are fixed at the end portions thereof to round shafts having various diameters, for example, about 22.2 mm or 23.8 mm, retainers whose substantially U-shaped longitudinal bodies have inner circumferential sizes that allow the retainers to be fitted over outer circumferences of the round shafts are required to be prepared for the round shafts having various diameters. Moreover, when the retainer which is formed of metal material is directly fitted over the metal-made round shaft, there is a possibility that noise will be produced by rubbing the metal-made retainer with the metal-made round shaft. In order to prevent the production of the noise, application of a resin coating onto the retainer is required, thus resulting in increased cost of the retainer.
- It is therefore an object of the present invention to provide an attaching device for fixing end portions of springs to a round shaft, which can overcome the foregoing problem associated with a diameter of the round shaft to which the attaching device is applied, is inexpensive, and can prevent noise from being generated due to rubbing of the attaching device with the round shaft.
- It is another object of the present invention to provide an attaching device for fixing end portions of springs to a round shaft, which can cause the end portions of the springs to be stably fixed to the round shaft and can be applied to the round shaft with simple operation.
- In accordance with the present invention, there is provided an attaching device for fixing an end portion of at least one spring for supporting a cushion for a seat, to a seat frame of the seat, wherein the seat frame includes opposing seat frame sections, one of the opposing seat frame sections being formed from a round shaft, the at least one spring being stretched between the opposing seat frame sections, the end portion of the at least one spring being formed substantially in a U-shape in outline and including first and second spaced apart axial regions and an intermediate axial region interconnecting the first and second spaced apart axial regions. The attaching device comprises a resin-made collar of a substantially U-shape in cross-section, and a metal-made retainer including a body having a geometry of similar figure with the collar, and at least one pair of first and second spring engagement pieces provided at both edges of the body, the first spring engagement piece extending downward from one of the both edges of the body and bent laterally outwardly at a lower end thereof for engaging with the first axial region of the at least one spring, the second spring engagement piece extending downward from the other of the both edges of the body and bent laterally outwardly at a lower end thereof for engaging with the second axial region of the at least one spring, the resin-made collar being adapted to be fitted over or mounted on the round shaft with an opening side thereof facing downward, the body of the retainer being adapted to be fitted over or mounted on the collar on the round shaft with the first spring engagement piece being located inside the seat frame and with the second spring engagement piece being located outside the seat frame, the first axial region and the second axial region of the at least one spring being adapted to be engaged with the first spring engagement piece and the second spring engagement piece, respectively, and the intermediate axial region of the at least one spring being adapted to be located under the round shaft, whereby the end portion of the at least one spring is adapted to be fixed to the round shaft.
- The attaching device of the present invention which is constructed as discussed above comprises the resin-made collar having a substantially U-shape in cross-section and adapted to be fitted over the round shaft, and the metal-made retainer adapted to be fitted over the resin-made collar on the round shaft, so that even if there is a size difference between an outer circumference of the round shaft and an inner circumference of the resin-made collar, such a size difference can be easily cancelled by elastic deformation of the resin-made collar. More particularly, in a case where the attaching device is applied to a round shaft having a diameter slightly larger than the inner circumference of the collar, fitting of the collar over the round shaft can be easily performed while causing the collar to be deformed in such a manner that an opening of the collar is operatively widened. Even if the attaching device is applied to a round shaft having a diameter smaller than the inner circumference of the collar and a clearance between the round shaft and the collar is produced, production of noise between the attaching device and the round shaft can be effectively prevented by the resin-made collar. Therefore, in order to prevent the production of the noise, application of a resin coating or the like onto the attaching device is not required, thus resulting in reduced cost of the attaching device.
- In a preferred embodiment according to the present invention, the first spring engagement piece may be formed so as to have a length which allows the at least one spring to be stretched between the opposing frame sections at a reference height and the second spring engagement piece may be formed so as to have a length relatively shorter than the first spring engagement piece, so that the end portion of the at least one spring is adapted to be fixed to the round shaft with the second axial region thereof being engaged with the second spring engagement piece at a position higher than a position where the first axial region is engaged with the first spring engagement piece, and with the intermediate axial region becoming oblique. In this case, the rear end portion of the spring is interposedly held by the first and second spring engagement pieces with the second axial region thereof in engagement with the second spring engagement piece being situated at a height higher than the first axial region thereof in engagement with the first spring engagement piece, and with the intermediate axial region becoming oblique. Thus, the spring can be stably stretched between the opposing seat frame sections by the attaching device so as to be located at the reference height.
- In a preferred embodiment according to the present invention, a plurality of springs may be stretched between the opposing frame sections so as to be spaced apart from one another, and the collar and the body of the retainer may be formed longitudinally, the longitudinal body of the retainer having pairs of first and second spring engagement pieces provided at both edges of the longitudinal body, and the pairs of first and second spring engagement pieces corresponding in number to the springs. In this case, the collar which is adapted to be fitted over the round shaft is formed longitudinally and the retainer which includes the longitudinal body and the pairs of first and second spring engagement pieces provided at the both edges of the longitudinal body, so that end portions of the plurality of springs can be easily fixed to the single round shaft by the attaching device.

FIG. 8 is a schematic view which is of assistance in explaining the seat cushion frame in a condition where an occupant sits on the vehicle seat. - Referring to
FIG. 1 , there is illustrated a seat cushion frame for a slide-type vehicle seat, in which springs are employed as means to support a cushion for a seat cushion of the vehicle seat and fixed at end portions thereof to the seat cushion frame by an attachingdevice 6 for fixing end portions of springs according to an embodiment of the present invention. The seat cushion frame comprises a pair of spaced apart left and rightside frame sections upper rail members side frame sections round shaft 3 formed from a round pipe or round rod, theround shaft 3 being attached between rear end portions of theside frame sections pan frame member 4 attached between forward end portions of theside frame sections FIG. 1 ,reference numerals upper rail members - In the seat cushion frame, a plurality of
springs 7, each of which constitutes a zigzag spring comprising a plurality of substantially U-shaped axial portions continuously connected to one another, are stretched between theround shaft 3 and thepan frame member 4 so as to be arranged in parallel with one another and spaced apart from one another. Thesprings 7 are horizontally stretched between theround shaft 3 and thepan frame member 4 by causingrear end portions 7 a of thesprings 7 to be fixed to theround shaft 3 through the attachingdevice 6 and by causing forward end portions of thesprings 7 to be hooked on loop-shapedengaging pieces 8 which are provided at thepan frame member 4 by causing regions of thepan frame member 4 to be cut and then causing the cut regions of thepan frame member 4 to be raised up from a surface of thepan frame member 4. - In the illustrated example, the attaching
device 6 is designed such that it can fix rear end portions of four springs 7 (seeFIG. 1 ) to thesingle round shaft 3 while allowing thesprings 7 to be spaced apart from one another. Referring toFIGS. 2 and 3 , the attachingdevice 6 comprises a resin-madelongitudinal collar 6 a formed of elastically deformable resin material, for example, polypropylene or the like, and a metal-maderetainer 6 b formed of, for example, thin steel plate. - The resin-made
longitudinal collar 6 a is configured so as to have a substantially U-shape in cross-section which allows thelongitudinal collar 6 a to be mounted on or fitted over theround shaft 3. Thelongitudinal collar 6 a is fitted over theround shaft 3 with an opening side thereof facing downwardly. Moreover, thelongitudinal collar 6 a is configured so as to have a length which is enough for allowing the rear end portions of the foursprings 7 to be fixed to theround shaft 3. - The metal-made
retainer 6 b comprises alongitudinal body 60 of a substantially U-shape in cross-section and four pairs ofspring engagement pieces 61, 62 (only one pair ofspring engagement pieces FIGS. 2 and 3 ) provided along both longitudinal edges of the substantially U-shapedlongitudinal body 60 so as to be spaced apart from one another in the longitudinal direction of thelongitudinal body 60. Thelongitudinal body 60 of the metal-maderetainer 6 b is mounted on or fitted over thecollar 6 a fitted over theround shaft 3, with an opening side thereof facing downwardly. More particularly, thelongitudinal body 60 of theretainer 6 b is configured so as to have a geometry of similar figure with thecollar 6 a and an inner circumference size that allows thelongitudinal body 60 of theretainer 6 b to be fitted over an outer circumference of thelongitudinal collar 6 a. - The
longitudinal collar 6 a has three pairs of spaced apartelongated protrusions 63 which rise up from a longitudinal top surface of thelongitudinal collar 6 a in a state of being fitted over theround shaft 3 and are arranged so as to be spaced apart from one another in the longitudinal direction of thelongitudinal collar 6 a. Correspondingly, thelongitudinal body 60 of theretainer 6 b has three through-holes 64 which are formed in a longitudinal top surface of thelongitudinal body 60 in a state of being fitted over thecollar 6 a and in which theprotrusions 63 of theretainer 6 b are fitted. In order that strength of theretainer 6 b can be maintained, the through-holes 64 are formed in the longitudinal top surface of thelongitudinal body 60 which are remote from regions of thelongitudinal body 60 at which thespring engagement pieces - The
longitudinal collar 6 a further has circumferential retaining-flanges longitudinal body 60 of theretainer 6 b is fitted over thelongitudinal collar 6 a in the state of being fitted over theround shaft 3, both ends of thelongitudinal body 60 of theretainer 6 b are abutted against the circumferential retaining-flanges collar 6 whereby thelongitudinal body 60 of theretainer 6 b are positioned with respect to thecollar 6 a through the circumferential retaining-flanges collar 6 a can be reinforced, the both end portions of thecollar 6 a hascircumferential ribs collar 6 a and theretainer 6 b are provided as separate components and any resin coating or the like is not required to be applied to the attaching device, thus realizing a decrease in cost. - As shown in
FIGS. 3 and 4 , the attachingdevice 6 constructed as discussed above is applied to theround shaft 3 with the resin-madecollar 6 a being fitted over theround shaft 3 and with the metal-maderetainer 6 b being fitted over thecollar 6 a on theround shaft 3. In the combination comprising the attachingdevice 6 and theround shaft 3 of the seat cushion frame, the firstspring engagement pieces 61 of theretainer 6 b fitted over thecollar 6 a downward extend beyond the round shaft and are located inside the seat cushion frame and the secondspring engagement pieces 62 of theretainer 6 b downward extend beyond theround shaft 3 and are located outside the seat cushion frame. - More particularly, the first
spring engagement pieces 61 and the secondspring engagement pieces 62 extend downward from one of the both longitudinal edges of thelongitudinal body 60 of theretainer 6 b and the other of the both longitudinal edges of thelongitudinal body 60, respectively, and are laterally outwardly bent at lower ends thereof in the opposite directions. Each of the firstspring engagement pieces 61 is formed in substantially a J-shape and has a length which allows a corresponding spring to be horizontally stretched between thepan frame section 4 and theround shaft 3 at a reference height. Each of the secondspring engagement pieces 62 is formed in substantially a U-shape and has a length relatively shorter than that of the first spring engagement piece. - Referring to
FIG. 5 , therear end portion 7 a of each of the springs 7 (only onespring 7 is shown inFIG. 5 ) is formed in substantially a U-shape in outline and comprises a pair of spaced apartaxial regions axial region 73 interconnecting the spaced apartaxial regions spring 7 is fixed to theround shaft 3 with the firstaxial region 71 thereof being engaged with a corresponding firstspring engagement piece 61 of theretainer 6 b, with the intermediateaxial region 73 thereof being located under theround shaft 3, and with the secondaxial region 72 thereof being engaged with a corresponding secondspring engagement piece 62 of theretainer 6 b. In this way, therear end portion 7 a of thespring 7 is interposedly held by the first and secondspring engagement pieces retainer 6 b. - Referring to
FIG. 6 , therear end portion 7 a of thespring 7 is interposedly held by the first and secondspring engagement pieces axial region 72 thereof in engagement with the secondspring engagement piece 62 being situated at a height higher than the firstaxial region 71 thereof in engagement with the firstspring engagement piece 61, and with the intermediateaxial region 73 becoming oblique. Thus, thesprings 7 can be stably stretched between theround shaft 3 and thepan frame member 4 by the attachingdevice 6 so as to become horizontal at the reference height. - When the end portions of the plurality of
springs 7 are to be fixed to theround shaft 3 by the attachingdevice 6 according to the embodiment of the present invention, thelongitudinal collar 6 a is fitted over theround shaft 3 and thelongitudinal body 60 of theretainer 6 b having the pairs ofspring engagement pieces springs 7 is then fitted over thelongitudinal collar 6 a, so that the attachingdevice 6 can be easily applied to theround shaft 3 with simple operation. - Referring to
FIG. 7 , there is illustrated a condition where thecollar 6 a is fitted over theround shaft 3 and thelongitudinal body 60 of theretainer 6 b is fitted over thecollar 6 a on theround shaft 3. The fitting of thelongitudinal body 60 of theretainer 6 b over thecollar 6 a on theround shaft 3 is performed while causing the through-holes 64 of theretainer 6 b to be engagedly fitted over theprotrusions 63 of thecollar 6 a. Thus, thelongitudinal body 60 ofretainer 6 b can be prevented from being rotated or circumferentially shifted relative to thecollar 6 a by the engagement of the through-holes 64 with theprotrusions 63. Moreover, the both end portions of thelongitudinal body 60 of theretainer 6 b on thecollar 6 a are abutted against the circumferential retaining-flanges collar 6 a and positioned by the circumferential retaining-flanges longitudinal body 60 over thecollar 6 b on theround shaft 3 can be correctly performed. - As discussed above, the resin-made
collar 6 a is fitted over theround shaft 3 and the metal-maderetainer 6 b is then fitted over the resin-madecollar 6 a on theround shaft 3, so that even if there is a size difference between an outer circumference of theround shaft 3 and an inner circumference of the resin-madecollar 6 a having a substantially U-shape in cross-section, such a size difference can be easily cancelled by elastic deformation of the resin-madecollar 6 a. More particularly, in a case where the attachingdevice 6 is applied to a round shaft having a diameter slightly larger than the inner circumference of thecollar 6 a, fitting of thecollar 6 a over theround shaft 3 can be easily performed while causing thecollar 6 a to be deformed in such a manner that an opening of thecollar 6 a is operatively widened. Even if the attachingdevice 6 is applied to a round shaft having a diameter smaller than the inner circumference of thecollar 6 a and a clearance between the round shaft and thecollar 6 a is produced, production of noise between the attachingdevice 6 and the round shaft can be effectively prevented by the resin-madecollar 6 a. - In the vehicle seat in which the
springs 7 are fixed to theround shaft 3 of the seat cushion frame through the attachingdevice 6 according to the embodiment of the present invention, when an occupant sits on the vehicle seat and the weight load of the occupant is then applied to the seat cushion, thesprings 7 are made to downwardly flex as shown inFIG. 8 . At this time, even if the attachingdevice 6 is pulled downward by the downward flexing of thesprings 7 and a force which tends to cause the attachingdevice 6 to be rotated relative to theround shaft 3 is thus applied to the attachingdevice 6 by the firstaxial regions 71 of thesprings 7 in engagement with the firstspring engagement pieces 61 inside the seat cushion frame, an opposing force is produced by the secondaxial regions 72 of thesprings 7 which are engagedly retained by the secondspring engagement pieces 62 of thedevice 6 outside the seat cushion frame. - The opposing force acts as a return torque since the
spring engagement pieces retainer 6 b are nipped by the first and secondaxial regions springs 7, so that thecollar 6 a andlongitudinal body 60 of theretainer 6 b are not rotated relative to theround shaft 3 and are maintained in the mounted condition where the opening side of thecollar 6 a and the opening side of thelongitudinal body 60 of theretainer 6 b face downward. Therefore, it is a matter of course that any noise is not generated between theround shaft 3 and the attachingdevice 6 since the attachingdevice 6 is not swung or rotated relative to theround shaft 3 when thesprings 7 are pulled downward and made to flex. In addition, theretainer 6 b is not deformed even if it is pulled by thesprings 7. - While the case where the round shaft is employed as a member constituting a rear frame section of the seat cushion frame has been discussed above, the present invention may be applied to a seat cushion frame in which a round shaft is employed in lieu of the pan frame member. Moreover, while the case where the rear end portions of the plurality of
springs 7 to be stretched between the rear frame section and the forward frame section are fixed to the rear frame section by the single attaching device has been discussed above, the present invention may be applied to a case where the attaching device is designed such that it comprises a plurality of short length collars and a plurality of retainers having short length bodies, which correspond in number to the springs and are constructed substantially in the same manner as the above-mentioned collar and retainer are done. More particularly, each of the collars includes at least one pair of elongated protrusions provided on a top surface thereof and circumferential retaining-flanges provided around both end portions thereof, and each of the retainer bodies includes a pair of first and second spring engagement pieces provided at both edges thereof and at least one through-hole formed in a top surface thereof. In this case, the collars are fitted over the round shaft so as to be spaced apart from one another, the retainer bodies are fitted over the collars with both end portions thereof being abutted against circumferential retaining-flanges of the collars and with through-holes thereof being fitted over elongated protrusions of the collars, and an end portion of each of the springs is fixed to the round shaft via corresponding one of the combinations comprising the collars and the retainers. - The terms and expressions which have been employed are used as terms of description and not of limitation, and there is no intention in the use of such terms and expressions of excluding any equivalents of the features shown and described, or portion thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
