The present invention relates to a vehicle door trim, which is attached to a fixed body having an opening or attached to a vehicle door, which is a movable body for opening and closing such an opening of a fixed body. The present invention also relates to a method for manufacturing the vehicle door trim.
Japanese Laid-Open Patent Publication No. 11-72395 discloses a conventional vehicle door panel attached to a door panel, which is a movable body of a sliding door. The vehicle door trim according to the publication is formed by an elongated rubber member and is attached to a door panel along a trim attaching part provided on the front edge of the door panel. The door trim has a single substantially U-shaped attaching portion, which is assembled to a single attaching piece (a flange in the above publication) provided at the trim attaching part. When the door panel is in a closed state, the door trim is located between the door trim attaching part of the door and the center pillar, which is a fixed body.
The trim attaching part of a door panel (or a center pillar), to which the door trim as described above is attached, has a shape in accordance with the shape of the door. Depending on the type of a vehicle, the trim attaching part is curved in the vehicle width direction. In such a case, if the attaching portion of the door trim is formed to be continuous in the longitudinal direction of the door trim, it is difficult to attach the door trim attaching portion to the curved section of the door trim attaching part. Thus, there is still room for improvement in this regard.
Accordingly, it is an objective of the present invention to provide a vehicle door trim that can be easily attached to a trim attaching part and a method for manufacturing the door trim.
To achieve the foregoing objective and in accordance with a first aspect of the present invention, an elongated vehicle door trim is provided that is adapted for being attached to a vehicle that has a fixed body having an opening and a movable body for opening and closing the opening. The door trim is attached along a trim attaching part of at least one of the fixed body and the movable body. When the movable body is in a closed state, the door trim is located between the movable body and the fixed body. The door trim comprises a plurality of attaching portions for being attached to the trim attaching part. The attaching portions are arranged along a longitudinal dimension of the door trim at predetermined intervals and formed integrally with the door trim.
In accordance with a second aspect of the present invention, a method for manufacturing an elongated vehicle door trim is provided. The door trim is adapted for being attached to a vehicle that has a fixed body having an opening and a movable body for opening and closing the opening. The door trim is adapted for being attached along a trim attaching part of at least one of the fixed body and the movable body such that when the movable body is in a closed state, the door trim is located between the movable body and the fixed body. The method comprising forming a plurality of attaching portions for being attached to the trim attaching part such that the attaching portions are formed integrally with the door trim and such that the attaching portions are arranged along a longitudinal dimension of the door trim at predetermined intervals.
Other aspects and advantages of the present invention will become apparent from the following description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the invention.

As shown in
A plurality of locking holes 5d are formed in and extend through the trim attaching part 5b. The locking holes 5d are spaced apart at equal intervals in the longitudinal direction of the trim attaching part 5b. Each locking hole 5d receives one of the locking projections 43 of the door trim 40. The locking portion 43b at the distal end of each locking projection 43 is locked to the back of the trim attaching part 5b, that is, locked to the end face opposite to the attaching surface 5c. This fixes the door trim 40 to the trim attaching part 5b. When installing the door trim 40, the door trim 40 is pressed in a direction toward the rear of the vehicle, against the trim attaching part 5b, so that the locking projections 43 are inserted into the locking holes 5d.
The door trim 40 of the present embodiment is installed while being curved in the vehicle width direction to correspond to the shape of the front edge 5a of the door panel 5 as shown in
The sensor portion 42 of the door trim 40 is used for detecting a foreign object X (see
The foreign object detection sensor 51 includes a hollow insulator 52. The hollow insulator 52 is formed of a tubular insulating material that has insulation properties and restoring characteristics and can be elastically deformed. The hollow insulator 52 is formed, for example, of soft plastic material, which is, for example, rubber. A separation hole 52a is formed in the radial center of the hollow insulator 52. The separation hole 52a is a through hole extending along the entire longitudinal dimension of the hollow insulator 52.
A pair of detection electrodes 53, 54 are arranged inside and held by the hollow insulator 52. The detection electrodes 53, 54 each include a flexible core electrode and a tubular elastic conductive coating layer (neither is shown). The core electrode is formed by twining conductive fine lines, and coated with the conductive coating layer. The two detection electrodes 53, 54 are arranged in the hollow insulator 52 separated from each other and extend helically along the longitudinal dimension of the hollow insulator 52. In the present embodiment, the pair of detection electrodes 53, 54 located inside the hollow insulator 52 face each other in a radial direction of the hollow insulator 52 at any position in the longitudinal direction of the hollow insulator 52. Approximately half the circumference of each of the detection electrodes 53, 54 is embedded in the hollow insulator 52.
Also, as shown in
The feeder cables 56, 57 are drawn into the door panel 5. The feeder cable 56, which is connected to the detection electrode 53, is electrically connected to a current passage detecting portion 58 (see

Operation of the electric sliding door apparatus 1 will now be described.
When receiving an opening signal from the operation switch 31, the door ECU 61 drives the slide actuator 25 to perform an opening operation of the door panel 5. Based on a position detection signal sent from the position detector 27, the door ECU 61 monitors the position of the door panel 5. In the present embodiment, the door ECU 61 counts the number of pulses of the position detection signal, and monitors the position of the door panel 5 based on the count value. When the door panel 5 is at a full open position Po, where it fully opens the entry/exit opening 4 (see
In contrast, when receiving a closing signal from the operation switch 31, the door ECU 61 drives the slide actuator 25 to perform a closing operation of the door panel 5. When the door panel 5 is at a fully closed position Pc, where it fully closes the entry/exit opening 4 (see
A method for manufacturing the door trim 40 will now be described. Through extrusion, the sensor holding portion 44 of the sensor portion 42, the base 41, and the locking projections 43 of the door trim 40 are integrally formed. That is, when the extrusion is finished, the locking projections 43 are continuous along the entire length of the door trim 40 as shown in
Operation of the above described embodiment will now be described.
As shown in
In the present embodiment, since the locking projections 43, which are directly locked to the trim attaching part 5b, are integrally formed with the door trim 40, no intervening members such as clips for being placed between the door trim 40 and the trim attaching part 5b are required. Therefore, since no intervening members such as clips need to be installed in the door trim 40, the manufacturing procedure is simplified, and the number of components is limited.
Next, advantages of the present embodiment will be described.
(1) The door trim 40 is attached along the trim attaching part 5b of the door panel 5, which opens and closes an opening (entry/exit opening 4). When the door panel 5 is in a closed state, the door trim 40 is located between the door panel 5 and the center pillar 7. The door trim 40 has integrally formed locking projections 43 for being attached to the trim attaching part 5b, and the locking projections 43 are arranged along the longitudinal dimension at predetermined intervals. The locking projections 43 are not located at the curved section R of the trim attaching part 5b, so the door trim 40 can be easily attached to the trim attaching part 5b while ensuring the fastening strength.
(2) Since the door trim 40 is formed by a resin member subjected to extrusion, the locking projections 43, which are integrally formed with the door trim 40, can be formed easily.
(3) Since the locking projections 43, which are directly locked to the trim attaching part 5b, are integrally formed with the door trim 40, no intervening members such as clips for being placed between the door trim 40 and the trim attaching part 5b are required. Therefore, since no intervening members such as clips, which are separate members, need to be installed in the door trim 40, the manufacturing procedure is simplified, and the number of components is limited.
(4) After the door trim 40 is extruded, unnecessary parts except for the parts corresponding to the locking projections 43 are removed from the continuous portion L, which includes the locking projections 43, so that the locking projections 43 are formed. Therefore, the locking projections 43 are easily formed at positions at predetermined intervals in the longitudinal direction of the door trim 40.
(5) Since the rear end face (the flat end face 41a) of the base 41 of the door trim 40 faces the trim attaching part 5b in the forward-rearward direction of the vehicle, the door trim 40 is prevented from chattering.
The embodiment of the present invention may be modified as follows.
In the above illustrated embodiment, attaching portions for being attached to the trim attaching part 5b are the locking projections 43. However, the present invention is not limited to these. For example, the structures illustrated in
According to the structure illustrated in
A plastic clip 74 is attached to each attaching hole 73 of the door trim 40. The clips 74 are intervening members between the door trim 40 and the trim attaching part 5b. Each clip 74 has a base portion 74a, which is attached to the corresponding attaching recess 71. A front end face of the base portions 74a contacts the attaching recess 71 of the base, and a rear end face of the base portion 74a contacts the attaching surface 5c of the trim attaching part 5b. Accordingly, the attaching recess 71 of the base 41 of the door trim 40 is supported by the base portions 74a of the clips 74 in the forward-rearward direction of the vehicle. A columnar insertion portion 74b extends in the vehicle width from the base portion 74a. The insertion portions 74b are passed through the attaching holes 73 of the base 41. A locking flange 74c is formed at the distal end of the insertion portion 74b, which projects from the attaching hole 73. The locking flange 74c is locked to the flat surface 72 of the base 41 in the width direction, which prevents the insertion portion 74b from escaping from the attaching hole 73.
Each clip 74 has an extended portion 74d extending toward the rear of the vehicle from the base portion 74a and a locking portion 74e formed at the distal end of the extended portion 74d. The extended portion 74d and the locking portion 74e have the same shapes as the extended portion 43a and the locking portion 43b of the above illustrated embodiment, and are inserted into and fixed to the locking hole 5d of the trim attaching part 5b. In this manner, the door trim 40 is fixed to the trim attaching part 5b via the clips 74 attached to the attaching holes 73.
In the structure shown in
In a structure in which intervening members (the clips 74) are provided between the door trim 40 and the trim attaching part 5b, a gap in the vehicle forward-rearward direction is formed between the attaching recess 71 and the trim attaching part 5b at sections where the clips 74 are not provided (each section between adjacent clips 74 in the longitudinal direction). The gaps may cause the door trim 40 to be flexed toward the rear of the vehicle. In this respect, in the configuration shown in
The attaching holes 73 of the present embodiment are successively formed in the width direction during the extrusion of the door trim 40 with a jig (not shown). Since the attaching holes 73 are formed simultaneously with the extrusion of the door trim 40, the manufacturing procedure of the door trim 40 is simplified.
In the structure shown in
The bracket 75 shown in
The first plate portion 75a of the bracket 75 has two insertion holes 75e, and screws 76 inserted in the insertion holes 75e are fastened to the trim attaching part 5b. This fixes the door trim 40 to the trim attaching part 5b with the bracket 75 in between. This configuration provides substantially the same advantages as the configuration shown in
In a structure illustrated in
A clip 83, which is an intervening member, is attached to each attaching hole 82. Each clip 83 has a head 83a, which is fitted into the hollow portion 81, an extended portion 83b, which extends toward the rear of the vehicle from the head 83a, and a locking flange 83c, which is provided at distal end of the extended portion 83b, that is, at the end opposite to the head 83a. The head 83a is locked to the inner surface of the hollow portion 81 to prevent the clip 83 from falling off the attaching hole 82. The extended portion 83b is passed through the corresponding attaching hole 82 of the door trim 40 and the corresponding locking hole 5d of the trim attaching part 5b. The locking flange 83c, which protrudes toward the rear of the vehicle from the locking hole 5d, is locked to the back side of the trim attaching part 5b, that is, locked to the end face opposite to the attaching surface 5c. This fixes the door trim 40 to the trim attaching part 5b with the clips 83 attached to the attaching holes 82. This configuration provides substantially the same advantages as the configuration shown in
In the above described embodiment, the locking projections 43 (attaching portions) are formed at equal intervals along the longitudinal dimension of the door trim 40. However, the locking projections 43 may be formed at unequal intervals. Also, in the structures shown in FIGS. 7A to 9B, the attaching holes 73, 82, which define attaching portions, may be arranged at unequal intervals along the longitudinal dimension.
In the above illustrated embodiment, the locking projections 43 are formed on the door trim 40, and the locking holes 5d, which are locked to the locking projections 43, are formed in the trim attaching part 5b. However, the positions of these projections and holes may be reversed.
In the illustrated embodiment, the door trim 40 is formed through extrusion. However, the door trim 40 may be formed through other method, for example, injection molding.
In the illustrated embodiment, the foreign object detection sensor 51 is formed by a pressure sensitive sensor. However, the foreign object detection sensor 51 may be formed, for example, by a proximity sensor. A configuration may be employed in which a foreign object detection sensor 51 that uses a pressure sensitive sensor and a proximity sensor together to detect a foreign object X.
In the illustrated embodiment, the foreign object detection sensor 51 is provided in the door trim 40. However, the foreign object detection sensor 51 may be omitted. For example, the sensor holding portion 44 may be replaced by a columnar portion (protector portion) having no hollow portion 44a.
The door trim 40 of the above embodiment may be formed of a plastic material other than rubber.
In the above embodiment, a foreign object detection sensor is provided on the slidable door panel 5, which selectively opens and closes an opening (the entry/exit opening 4) formed in a side of a vehicle. However, a foreign object detection sensor may be provided on a door panel 5 that is selectively opens and closes an opening at the back of the vehicle (tailgate). A foreign object detection sensor may be provided on a part of the vehicle body that faces the door panel 5 (on the edge of the opening).
In the above embodiment, a foreign object detection sensor is provided in the slidable door panel 5. However, a foreign object detection sensor may be provided in a door panel 5 that is rotational relative to the vehicle body 3, for example, via hinges.
In the above embodiment, the door trim 40 is provided on the door panel 5. In addition, another door trim 40 may be provided on the center pillar 7. In that case, the trim attaching part 5b is provided on the center pillar 7. Alternatively, a door trim 40 may be provided only on the center pillar 7.
In the above embodiment, the door trim 40 is fixed to the door panel 5 by means of the locking projections 43, which are integrally formed with the base 41 of the door trim 40. However, the door trim 40 may be fixed by a bonding member in addition to the locking projections 43.
For example, in a configuration shown in
According to this configuration, the door trim 40 is fixed not only by the locking projections 43, but also by the bonding member E. Thus, the attachment strength is improved by bonding, which is an easy method. By using the bonding member E for fixation at the curved section R of the door trim 40, where no locking projections 43 are formed, the attachment strength is improved without reducing the ease of attachment of the door trim 40. Also, in the configuration shown in
Although one locking projection 43 is provided at each end in the longitudinal direction of the door trim 40 in the configuration of
Therefore, the present examples and embodiments are to be considered as illustrative and not restrictive and the invention is not to be limited to the details given herein, but may be modified within the scope and equivalence of the appended claims.
